-## Java Versions
+## Supported Java Versions
+
+Java 8 or above is required for using this client.
+
+Google's Java client libraries,
+[Google Cloud Client Libraries][cloudlibs]
+and
+[Google Cloud API Libraries][apilibs],
+follow the
+[Oracle Java SE support roadmap][oracle]
+(see the Oracle Java SE Product Releases section).
+
+### For new development
+
+In general, new feature development occurs with support for the lowest Java
+LTS version covered by  Oracle's Premier Support (which typically lasts 5 years
+from initial General Availability). If the minimum required JVM for a given
+library is changed, it is accompanied by a [semver][semver] major release.
 
-Java 7 or above is required for using this client.
+Java 11 and (in September 2021) Java 17 are the best choices for new
+development.
+
+### Keeping production systems current
+
+Google tests its client libraries with all current LTS versions covered by
+Oracle's Extended Support (which typically lasts 8 years from initial
+General Availability).
+
+#### Legacy support
+
+Google's client libraries support legacy versions of Java runtimes with long
+term stable libraries that don't receive feature updates on a best efforts basis
+as it may not be possible to backport all patches.
+
+Google provides updates on a best efforts basis to apps that continue to use
+Java 7, though apps might need to upgrade to current versions of the library
+that supports their JVM.
+
+#### Where to find specific information
+
+The latest versions and the supported Java versions are identified on
+the individual GitHub repository `github.com/GoogleAPIs/java-SERVICENAME`
+and on [google-cloud-java][g-c-j].

-/**
- * Service Description: Cloud Tasks allows developers to manage the execution of background work in
- * their applications.
- *
- * <p>This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * <pre>{@code
- * try (CloudTasksClient cloudTasksClient = CloudTasksClient.create()) {
- *   QueueName name = QueueName.of("[PROJECT]", "[LOCATION]", "[QUEUE]");
- *   Queue response = cloudTasksClient.getQueue(name);
- * }
- * }</pre>
- *
- * <p>Note: close() needs to be called on the CloudTasksClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * <p>The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * <ol>
- *   <li>A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   <li>A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   <li>A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * </ol>
- *
- * <p>See the individual methods for example code.
- *
- * <p>Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * <p>This class can be customized by passing in a custom instance of CloudTasksSettings to
- * create(). For example:
- *
- * <p>To customize credentials:
- *
- * <pre>{@code
- * CloudTasksSettings cloudTasksSettings =
- *     CloudTasksSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
- * }</pre>
- *
- * <p>To customize the endpoint:
- *
- * <pre>{@code
- * CloudTasksSettings cloudTasksSettings =
- *     CloudTasksSettings.newBuilder().setEndpoint(myEndpoint).build();
- * CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
- * }</pre>
- *
- * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

-/**
- * Settings class to configure an instance of {@link CloudTasksClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (cloudtasks.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of getQueue to 30 seconds:
- *
- * <pre>{@code
- * CloudTasksSettings.Builder cloudTasksSettingsBuilder = CloudTasksSettings.newBuilder();
- * cloudTasksSettingsBuilder
- *     .getQueueSettings()
- *     .setRetrySettings(
- *         cloudTasksSettingsBuilder
- *             .getQueueSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * CloudTasksSettings cloudTasksSettings = cloudTasksSettingsBuilder.build();
- * }</pre>

-/**
- * Settings class to configure an instance of {@link CloudTasksStub}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (cloudtasks.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of getQueue to 30 seconds:
- *
- * <pre>{@code
- * CloudTasksStubSettings.Builder cloudTasksSettingsBuilder = CloudTasksStubSettings.newBuilder();
- * cloudTasksSettingsBuilder
- *     .getQueueSettings()
- *     .setRetrySettings(
- *         cloudTasksSettingsBuilder
- *             .getQueueSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * CloudTasksStubSettings cloudTasksSettings = cloudTasksSettingsBuilder.build();
- * }</pre>

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: Cloud Tasks allows developers to manage the execution of background work in
- * their applications.
- *
- * <p>This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * <pre>{@code
- * try (CloudTasksClient cloudTasksClient = CloudTasksClient.create()) {
- *   QueueName name = QueueName.of("[PROJECT]", "[LOCATION]", "[QUEUE]");
- *   Queue response = cloudTasksClient.getQueue(name);
- * }
- * }</pre>
- *
- * <p>Note: close() needs to be called on the CloudTasksClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * <p>The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * <ol>
- *   <li>A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   <li>A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   <li>A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * </ol>
- *
- * <p>See the individual methods for example code.
- *
- * <p>Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * <p>This class can be customized by passing in a custom instance of CloudTasksSettings to
- * create(). For example:
- *
- * <p>To customize credentials:
- *
- * <pre>{@code
- * CloudTasksSettings cloudTasksSettings =
- *     CloudTasksSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
- * }</pre>
- *
- * <p>To customize the endpoint:
- *
- * <pre>{@code
- * CloudTasksSettings cloudTasksSettings =
- *     CloudTasksSettings.newBuilder().setEndpoint(myEndpoint).build();
- * CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
- * }</pre>
- *
- * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

-   *     to that of an existing task or a task that was deleted or completed recently then the call
-   *     will fail with [ALREADY_EXISTS][google.rpc.Code.ALREADY_EXISTS]. If the task's queue was

-   *     after the original task was deleted or completed.
-   *     <p>Because there is an extra lookup cost to identify duplicate task names, these

-   *     using a timestamp, causes an increase in latency and error rates in all task commands. The

-/**
- * Settings class to configure an instance of {@link CloudTasksClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (cloudtasks.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of getQueue to 30 seconds:
- *
- * <pre>{@code
- * CloudTasksSettings.Builder cloudTasksSettingsBuilder = CloudTasksSettings.newBuilder();
- * cloudTasksSettingsBuilder
- *     .getQueueSettings()
- *     .setRetrySettings(
- *         cloudTasksSettingsBuilder
- *             .getQueueSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * CloudTasksSettings cloudTasksSettings = cloudTasksSettingsBuilder.build();
- * }</pre>

-/**
- * Settings class to configure an instance of {@link CloudTasksStub}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (cloudtasks.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of getQueue to 30 seconds:
- *
- * <pre>{@code
- * CloudTasksStubSettings.Builder cloudTasksSettingsBuilder = CloudTasksStubSettings.newBuilder();
- * cloudTasksSettingsBuilder
- *     .getQueueSettings()
- *     .setRetrySettings(
- *         cloudTasksSettingsBuilder
- *             .getQueueSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * CloudTasksStubSettings cloudTasksSettings = cloudTasksSettingsBuilder.build();

-// AUTO-GENERATED DOCUMENTATION AND CLASS.
-/**
- * Service Description: Cloud Tasks allows developers to manage the execution of background work in
- * their applications.
- *
- * <p>This class provides the ability to make remote calls to the backing service through method
- * calls that map to API methods. Sample code to get started:
- *
- * <pre>{@code
- * try (CloudTasksClient cloudTasksClient = CloudTasksClient.create()) {
- *   QueueName name = QueueName.of("[PROJECT]", "[LOCATION]", "[QUEUE]");
- *   Queue response = cloudTasksClient.getQueue(name);
- * }
- * }</pre>
- *
- * <p>Note: close() needs to be called on the CloudTasksClient object to clean up resources such as
- * threads. In the example above, try-with-resources is used, which automatically calls close().
- *
- * <p>The surface of this class includes several types of Java methods for each of the API's
- * methods:
- *
- * <ol>
- *   <li>A "flattened" method. With this type of method, the fields of the request type have been
- *       converted into function parameters. It may be the case that not all fields are available as
- *       parameters, and not every API method will have a flattened method entry point.
- *   <li>A "request object" method. This type of method only takes one parameter, a request object,
- *       which must be constructed before the call. Not every API method will have a request object
- *       method.
- *   <li>A "callable" method. This type of method takes no parameters and returns an immutable API
- *       callable object, which can be used to initiate calls to the service.
- * </ol>
- *
- * <p>See the individual methods for example code.
- *
- * <p>Many parameters require resource names to be formatted in a particular way. To assist with
- * these names, this class includes a format method for each type of name, and additionally a parse
- * method to extract the individual identifiers contained within names that are returned.
- *
- * <p>This class can be customized by passing in a custom instance of CloudTasksSettings to
- * create(). For example:
- *
- * <p>To customize credentials:
- *
- * <pre>{@code
- * CloudTasksSettings cloudTasksSettings =
- *     CloudTasksSettings.newBuilder()
- *         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
- *         .build();
- * CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
- * }</pre>
- *
- * <p>To customize the endpoint:
- *
- * <pre>{@code
- * CloudTasksSettings cloudTasksSettings =
- *     CloudTasksSettings.newBuilder().setEndpoint(myEndpoint).build();
- * CloudTasksClient cloudTasksClient = CloudTasksClient.create(cloudTasksSettings);
- * }</pre>
- *
- * <p>Please refer to the GitHub repository's samples for more quickstart code snippets.

-/**
- * Settings class to configure an instance of {@link CloudTasksClient}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (cloudtasks.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of getQueue to 30 seconds:
- *
- * <pre>{@code
- * CloudTasksSettings.Builder cloudTasksSettingsBuilder = CloudTasksSettings.newBuilder();
- * cloudTasksSettingsBuilder
- *     .getQueueSettings()
- *     .setRetrySettings(
- *         cloudTasksSettingsBuilder
- *             .getQueueSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * CloudTasksSettings cloudTasksSettings = cloudTasksSettingsBuilder.build();
- * }</pre>

-/**
- * Settings class to configure an instance of {@link CloudTasksStub}.
- *
- * <p>The default instance has everything set to sensible defaults:
- *
- * <ul>
- *   <li>The default service address (cloudtasks.googleapis.com) and default port (443) are used.
- *   <li>Credentials are acquired automatically through Application Default Credentials.
- *   <li>Retries are configured for idempotent methods but not for non-idempotent methods.
- * </ul>
- *
- * <p>The builder of this class is recursive, so contained classes are themselves builders. When
- * build() is called, the tree of builders is called to create the complete settings object.
- *
- * <p>For example, to set the total timeout of getQueue to 30 seconds:
- *
- * <pre>{@code
- * CloudTasksStubSettings.Builder cloudTasksSettingsBuilder = CloudTasksStubSettings.newBuilder();
- * cloudTasksSettingsBuilder
- *     .getQueueSettings()
- *     .setRetrySettings(
- *         cloudTasksSettingsBuilder
- *             .getQueueSettings()
- *             .getRetrySettings()
- *             .toBuilder()
- *             .setTotalTimeout(Duration.ofSeconds(30))
- *             .build());
- * CloudTasksStubSettings cloudTasksSettings = cloudTasksSettingsBuilder.build();

-/**
- *
- *
- * <pre>
- * App Engine HTTP request.
- * The message defines the HTTP request that is sent to an App Engine app when
- * the task is dispatched.
- * Using [AppEngineHttpRequest][google.cloud.tasks.v2.AppEngineHttpRequest] requires
- * [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
- * Google IAM permission for the project
- * and the following scope:
- * `https://www.googleapis.com/auth/cloud-platform`
- * The task will be delivered to the App Engine app which belongs to the same
- * project as the queue. For more information, see
- * [How Requests are
- * Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
- * and how routing is affected by
- * [dispatch
- * files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
- * Traffic is encrypted during transport and never leaves Google datacenters.
- * Because this traffic is carried over a communication mechanism internal to
- * Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
- * The request to the handler, however, will appear to have used the HTTP
- * protocol.
- * The [AppEngineRouting][google.cloud.tasks.v2.AppEngineRouting] used to construct the URL that the task is
- * delivered to can be set at the queue-level or task-level:
- * * If [app_engine_routing_override is set on the
- *    queue][Queue.app_engine_routing_override], this value is used for all
- *    tasks in the queue, no matter what the setting is for the [task-level
- *    app_engine_routing][AppEngineHttpRequest.app_engine_routing].
- * The `url` that the task will be sent to is:
- * * `url =` [host][google.cloud.tasks.v2.AppEngineRouting.host] `+`
- *   [relative_uri][google.cloud.tasks.v2.AppEngineHttpRequest.relative_uri]
- * Tasks can be dispatched to secure app handlers, unsecure app handlers, and
- * URIs restricted with
- * [`login:
- * admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
- * Because tasks are not run as any user, they cannot be dispatched to URIs
- * restricted with
- * [`login:
- * required`](https://cloud.google.com/appengine/docs/standard/python/config/appref)
- * Task dispatches also do not follow redirects.
- * The task attempt has succeeded if the app's request handler returns an HTTP
- * response code in the range [`200` - `299`]. The task attempt has failed if
- * the app's handler returns a non-2xx response code or Cloud Tasks does
- * not receive response before the [deadline][google.cloud.tasks.v2.Task.dispatch_deadline]. Failed
- * tasks will be retried according to the
- * [retry configuration][google.cloud.tasks.v2.Queue.retry_config]. `503` (Service Unavailable) is
- * considered an App Engine system error instead of an application error and
- * will cause Cloud Tasks' traffic congestion control to temporarily throttle
- * the queue's dispatches. Unlike other types of task targets, a `429` (Too Many
- * Requests) response from an app handler does not cause traffic congestion
- * control to throttle the queue.
- * </pre>
- *
- * Protobuf type {@code google.cloud.tasks.v2.AppEngineHttpRequest}

-   *
-   *
-   * <pre>
-   * App Engine HTTP request.
-   * The message defines the HTTP request that is sent to an App Engine app when
-   * the task is dispatched.
-   * Using [AppEngineHttpRequest][google.cloud.tasks.v2.AppEngineHttpRequest] requires
-   * [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
-   * Google IAM permission for the project
-   * and the following scope:
-   * `https://www.googleapis.com/auth/cloud-platform`
-   * The task will be delivered to the App Engine app which belongs to the same
-   * project as the queue. For more information, see
-   * [How Requests are
-   * Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
-   * and how routing is affected by
-   * [dispatch
-   * files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
-   * Traffic is encrypted during transport and never leaves Google datacenters.
-   * Because this traffic is carried over a communication mechanism internal to
-   * Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
-   * The request to the handler, however, will appear to have used the HTTP
-   * protocol.
-   * The [AppEngineRouting][google.cloud.tasks.v2.AppEngineRouting] used to construct the URL that the task is
-   * delivered to can be set at the queue-level or task-level:
-   * * If [app_engine_routing_override is set on the
-   *    queue][Queue.app_engine_routing_override], this value is used for all
-   *    tasks in the queue, no matter what the setting is for the [task-level
-   *    app_engine_routing][AppEngineHttpRequest.app_engine_routing].
-   * The `url` that the task will be sent to is:
-   * * `url =` [host][google.cloud.tasks.v2.AppEngineRouting.host] `+`
-   *   [relative_uri][google.cloud.tasks.v2.AppEngineHttpRequest.relative_uri]
-   * Tasks can be dispatched to secure app handlers, unsecure app handlers, and
-   * URIs restricted with
-   * [`login:
-   * admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
-   * Because tasks are not run as any user, they cannot be dispatched to URIs
-   * restricted with
-   * [`login:
-   * required`](https://cloud.google.com/appengine/docs/standard/python/config/appref)
-   * Task dispatches also do not follow redirects.
-   * The task attempt has succeeded if the app's request handler returns an HTTP
-   * response code in the range [`200` - `299`]. The task attempt has failed if
-   * the app's handler returns a non-2xx response code or Cloud Tasks does
-   * not receive response before the [deadline][google.cloud.tasks.v2.Task.dispatch_deadline]. Failed
-   * tasks will be retried according to the
-   * [retry configuration][google.cloud.tasks.v2.Queue.retry_config]. `503` (Service Unavailable) is
-   * considered an App Engine system error instead of an application error and
-   * will cause Cloud Tasks' traffic congestion control to temporarily throttle
-   * the queue's dispatches. Unlike other types of task targets, a `429` (Too Many
-   * Requests) response from an app handler does not cause traffic congestion
-   * control to throttle the queue.

-   * a task's ID is identical to that of an existing task or a task
-   * that was deleted or executed recently then the call will fail
-   * with [ALREADY_EXISTS][google.rpc.Code.ALREADY_EXISTS].
-   * If the task's queue was created using Cloud Tasks, then another task with
-   * the same name can't be created for ~1hour after the original task was
-   * deleted or executed. If the task's queue was created using queue.yaml or
-   * queue.xml, then another task with the same name can't be created
-   * for ~9days after the original task was deleted or executed.
-   * Because there is an extra lookup cost to identify duplicate task
-   * names, these [CreateTask][google.cloud.tasks.v2.CloudTasks.CreateTask] calls have significantly
-   * increased latency. Using hashed strings for the task id or for
-   * the prefix of the task id is recommended. Choosing task ids that
-   * are sequential or have sequential prefixes, for example using a
-   * timestamp, causes an increase in latency and error rates in all
-   * task commands. The infrastructure relies on an approximately
-   * uniform distribution of task ids to store and serve tasks
-   * efficiently.

- * or the redirected worker acknowledges the task by returning a successful HTTP
- * response code ([`200` - `299`]), the task will be removed from the queue. If
- * any other HTTP response code is returned or no response is received, the
- * task will be retried according to the following:
- * * User-specified throttling: [retry configuration][google.cloud.tasks.v2.Queue.retry_config],
- *   [rate limits][google.cloud.tasks.v2.Queue.rate_limits], and the [queue's state][google.cloud.tasks.v2.Queue.state].
- * * System throttling: To prevent the worker from overloading, Cloud Tasks may
- *   temporarily reduce the queue's effective rate. User-specified settings
- *   will not be changed.
- *  System throttling happens because:
- *   * Cloud Tasks backs off on all errors. Normally the backoff specified in
- *     [rate limits][google.cloud.tasks.v2.Queue.rate_limits] will be used. But if the worker returns
- *     `429` (Too Many Requests), `503` (Service Unavailable), or the rate of
- *     errors is high, Cloud Tasks will use a higher backoff rate. The retry
- *     specified in the `Retry-After` HTTP response header is considered.
- *   * To prevent traffic spikes and to smooth sudden increases in traffic,
- *     dispatches ramp up slowly when the queue is newly created or idle and
- *     if large numbers of tasks suddenly become available to dispatch (due to
- *     spikes in create task rates, the queue being unpaused, or many tasks

-   *
-   * <pre>
-   * HTTP request.
-   * The task will be pushed to the worker as an HTTP request. If the worker
-   * or the redirected worker acknowledges the task by returning a successful HTTP
-   * response code ([`200` - `299`]), the task will be removed from the queue. If
-   * any other HTTP response code is returned or no response is received, the
-   * task will be retried according to the following:
-   * * User-specified throttling: [retry configuration][google.cloud.tasks.v2.Queue.retry_config],
-   *   [rate limits][google.cloud.tasks.v2.Queue.rate_limits], and the [queue's state][google.cloud.tasks.v2.Queue.state].
-   * * System throttling: To prevent the worker from overloading, Cloud Tasks may
-   *   temporarily reduce the queue's effective rate. User-specified settings
-   *   will not be changed.
-   *  System throttling happens because:
-   *   * Cloud Tasks backs off on all errors. Normally the backoff specified in
-   *     [rate limits][google.cloud.tasks.v2.Queue.rate_limits] will be used. But if the worker returns
-   *     `429` (Too Many Requests), `503` (Service Unavailable), or the rate of
-   *     errors is high, Cloud Tasks will use a higher backoff rate. The retry
-   *     specified in the `Retry-After` HTTP response header is considered.
-   *   * To prevent traffic spikes and to smooth sudden increases in traffic,
-   *     dispatches ramp up slowly when the queue is newly created or idle and
-   *     if large numbers of tasks suddenly become available to dispatch (due to
-   *     spikes in create task rates, the queue being unpaused, or many tasks
-   *     that are scheduled at the same time).
-   * </pre>

-   * Max burst size limits how fast tasks in queue are processed when
-   * many tasks are in the queue and the rate is high. This field
-   * allows the queue to have a high rate so processing starts shortly
-   * after a task is enqueued, but still limits resource usage when
-   * many tasks are enqueued in a short period of time.
-   * The [token bucket](https://wikipedia.org/wiki/Token_Bucket)
-   * algorithm is used to control the rate of task dispatches. Each
-   * queue has a token bucket that holds tokens, up to the maximum
-   * specified by `max_burst_size`. Each time a task is dispatched, a
-   * token is removed from the bucket. Tasks will be dispatched until
-   * the queue's bucket runs out of tokens. The bucket will be
-   * continuously refilled with new tokens based on
-   * [max_dispatches_per_second][google.cloud.tasks.v2.RateLimits.max_dispatches_per_second].
-   * Cloud Tasks will pick the value of `max_burst_size` based on the
-   * value of
-   * [max_dispatches_per_second][google.cloud.tasks.v2.RateLimits.max_dispatches_per_second].
-   * For queues that were created or updated using
-   * `queue.yaml/xml`, `max_burst_size` is equal to
-   * [bucket_size](https://cloud.google.com/appengine/docs/standard/python/config/queueref#bucket_size).
-   * Since `max_burst_size` is output only, if
-   * [UpdateQueue][google.cloud.tasks.v2.CloudTasks.UpdateQueue] is called on a queue
-   * created by `queue.yaml/xml`, `max_burst_size` will be reset based
-   * on the value of
-   * [max_dispatches_per_second][google.cloud.tasks.v2.RateLimits.max_dispatches_per_second],
-   * regardless of whether
-   * [max_dispatches_per_second][google.cloud.tasks.v2.RateLimits.max_dispatches_per_second]

-   * worker. For example, if the worker is stuck, it may not react to cancelled
-   * requests.
-   * The default and maximum values depend on the type of request:
-   * * For [HTTP tasks][google.cloud.tasks.v2.HttpRequest], the default is 10 minutes. The deadline
-   *   must be in the interval [15 seconds, 30 minutes].
-   * * For [App Engine tasks][google.cloud.tasks.v2.AppEngineHttpRequest], 0 indicates that the
-   *   request has the default deadline. The default deadline depends on the
-   *   [scaling
-   *   type](https://cloud.google.com/appengine/docs/standard/go/how-instances-are-managed#instance_scaling)
-   *   of the service: 10 minutes for standard apps with automatic scaling, 24
-   *   hours for standard apps with manual and basic scaling, and 60 minutes for
-   *   flex apps. If the request deadline is set, it must be in the interval [15
-   *   seconds, 24 hours 15 seconds]. Regardless of the task's
-   *   `dispatch_deadline`, the app handler will not run for longer than than
-   *   the service's timeout. We recommend setting the `dispatch_deadline` to
-   *   at most a few seconds more than the app handler's timeout. For more
-   *   information see
-   *   [Timeouts](https://cloud.google.com/tasks/docs/creating-appengine-handlers#timeouts).
-   * `dispatch_deadline` will be truncated to the nearest millisecond. The
-   * deadline is an approximate deadline.

-//
-//   * To prevent traffic spikes and to smooth sudden increases in traffic,
-//     dispatches ramp up slowly when the queue is newly created or idle and
-//     if large numbers of tasks suddenly become available to dispatch (due to

-/**
- *
- *
- * <pre>
- * App Engine HTTP request.
- * The message defines the HTTP request that is sent to an App Engine app when
- * the task is dispatched.
- * This proto can only be used for tasks in a queue which has
- * [app_engine_http_target][google.cloud.tasks.v2beta2.Queue.app_engine_http_target] set.
- * Using [AppEngineHttpRequest][google.cloud.tasks.v2beta2.AppEngineHttpRequest] requires
- * [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
- * Google IAM permission for the project
- * and the following scope:
- * `https://www.googleapis.com/auth/cloud-platform`
- * The task will be delivered to the App Engine app which belongs to the same
- * project as the queue. For more information, see
- * [How Requests are
- * Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
- * and how routing is affected by
- * [dispatch
- * files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
- * Traffic is encrypted during transport and never leaves Google datacenters.
- * Because this traffic is carried over a communication mechanism internal to
- * Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
- * The request to the handler, however, will appear to have used the HTTP
- * protocol.
- * The [AppEngineRouting][google.cloud.tasks.v2beta2.AppEngineRouting] used to construct the URL that the task is
- * delivered to can be set at the queue-level or task-level:
- * * If set,
- *   [app_engine_routing_override][google.cloud.tasks.v2beta2.AppEngineHttpTarget.app_engine_routing_override]
- *   is used for all tasks in the queue, no matter what the setting
- *   is for the
- *   [task-level app_engine_routing][google.cloud.tasks.v2beta2.AppEngineHttpRequest.app_engine_routing].
- * The `url` that the task will be sent to is:
- * * `url =` [host][google.cloud.tasks.v2beta2.AppEngineRouting.host] `+`
- *   [relative_url][google.cloud.tasks.v2beta2.AppEngineHttpRequest.relative_url]
- * Tasks can be dispatched to secure app handlers, unsecure app handlers, and
- * URIs restricted with
- * [`login:
- * admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
- * Because tasks are not run as any user, they cannot be dispatched to URIs

-   * Repeated headers are not supported but a header value can contain commas.
-   * Cloud Tasks sets some headers to default values:
-   * * `User-Agent`: By default, this header is
-   *   `"AppEngine-Google; (+http://code.google.com/appengine)"`.
-   *   This header can be modified, but Cloud Tasks will append
-   *   `"AppEngine-Google; (+http://code.google.com/appengine)"` to the
-   *   modified `User-Agent`.
-   * If the task has a [payload][google.cloud.tasks.v2beta2.AppEngineHttpRequest.payload], Cloud
-   * Tasks sets the following headers:
-   * * `Content-Type`: By default, the `Content-Type` header is set to
-   *   `"application/octet-stream"`. The default can be overridden by explicitly
-   *   setting `Content-Type` to a particular media type when the
-   *   [task is created][google.cloud.tasks.v2beta2.CloudTasks.CreateTask].
-   *   For example, `Content-Type` can be set to `"application/json"`.
-   * * `Content-Length`: This is computed by Cloud Tasks. This value is
-   *   output only.   It cannot be changed.
-   * The headers below cannot be set or overridden:
-   * * `Host`
-   * * `X-Google-*`
-   * * `X-AppEngine-*`
-   * In addition, Cloud Tasks sets some headers when the task is dispatched,
-   * such as headers containing information about the task; see
-   * [request
-   * headers](https://cloud.google.com/appengine/docs/python/taskqueue/push/creating-handlers#reading_request_headers).
-   * These headers are set only when the task is dispatched, so they are not
-   * visible when the task is returned in a Cloud Tasks response.
-   * Although there is no specific limit for the maximum number of headers or
-   * the size, there is a limit on the maximum size of the [Task][google.cloud.tasks.v2beta2.Task]. For more
-   * information, see the [CreateTask][google.cloud.tasks.v2beta2.CloudTasks.CreateTask] documentation.

-   *
-   *
-   * <pre>
-   * App Engine HTTP request.
-   * The message defines the HTTP request that is sent to an App Engine app when
-   * the task is dispatched.
-   * This proto can only be used for tasks in a queue which has
-   * [app_engine_http_target][google.cloud.tasks.v2beta2.Queue.app_engine_http_target] set.
-   * Using [AppEngineHttpRequest][google.cloud.tasks.v2beta2.AppEngineHttpRequest] requires
-   * [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
-   * Google IAM permission for the project
-   * and the following scope:
-   * `https://www.googleapis.com/auth/cloud-platform`
-   * The task will be delivered to the App Engine app which belongs to the same
-   * project as the queue. For more information, see
-   * [How Requests are
-   * Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
-   * and how routing is affected by
-   * [dispatch
-   * files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
-   * Traffic is encrypted during transport and never leaves Google datacenters.
-   * Because this traffic is carried over a communication mechanism internal to
-   * Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
-   * The request to the handler, however, will appear to have used the HTTP
-   * protocol.
-   * The [AppEngineRouting][google.cloud.tasks.v2beta2.AppEngineRouting] used to construct the URL that the task is
-   * delivered to can be set at the queue-level or task-level:
-   * * If set,
-   *   [app_engine_routing_override][google.cloud.tasks.v2beta2.AppEngineHttpTarget.app_engine_routing_override]
-   *   is used for all tasks in the queue, no matter what the setting
-   *   is for the
-   *   [task-level app_engine_routing][google.cloud.tasks.v2beta2.AppEngineHttpRequest.app_engine_routing].
-   * The `url` that the task will be sent to is:
-   * * `url =` [host][google.cloud.tasks.v2beta2.AppEngineRouting.host] `+`
-   *   [relative_url][google.cloud.tasks.v2beta2.AppEngineHttpRequest.relative_url]
-   * Tasks can be dispatched to secure app handlers, unsecure app handlers, and
-   * URIs restricted with
-   * [`login:
-   * admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
-   * Because tasks are not run as any user, they cannot be dispatched to URIs
-   * restricted with
-   * [`login:
-   * required`](https://cloud.google.com/appengine/docs/standard/python/config/appref)
-   * Task dispatches also do not follow redirects.
-   * The task attempt has succeeded if the app's request handler returns an HTTP
-   * response code in the range [`200` - `299`]. The task attempt has failed if
-   * the app's handler returns a non-2xx response code or Cloud Tasks does
-   * not receive response before the [deadline][Task.dispatch_deadline]. Failed
-   * tasks will be retried according to the
-   * [retry configuration][google.cloud.tasks.v2beta2.Queue.retry_config]. `503` (Service Unavailable) is
-   * considered an App Engine system error instead of an application error and
-   * will cause Cloud Tasks' traffic congestion control to temporarily throttle
-   * the queue's dispatches. Unlike other types of task targets, a `429` (Too Many
-   * Requests) response from an app handler does not cause traffic congestion
-   * control to throttle the queue.
-   * </pre>
-   *

-/**
- *
- *
- * <pre>
- * App Engine HTTP request.
- * The message defines the HTTP request that is sent to an App Engine app when
- * the task is dispatched.
- * Using [AppEngineHttpRequest][google.cloud.tasks.v2beta3.AppEngineHttpRequest] requires
- * [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
- * Google IAM permission for the project
- * and the following scope:
- * `https://www.googleapis.com/auth/cloud-platform`
- * The task will be delivered to the App Engine app which belongs to the same
- * project as the queue. For more information, see
- * [How Requests are
- * Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
- * and how routing is affected by
- * [dispatch
- * files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
- * Traffic is encrypted during transport and never leaves Google datacenters.
- * Because this traffic is carried over a communication mechanism internal to
- * Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
- * The request to the handler, however, will appear to have used the HTTP
- * protocol.
- * The [AppEngineRouting][google.cloud.tasks.v2beta3.AppEngineRouting] used to construct the URL that the task is
- * delivered to can be set at the queue-level or task-level:
- * * If set,
- *   [app_engine_routing_override][google.cloud.tasks.v2beta3.AppEngineHttpQueue.app_engine_routing_override]
- *   is used for all tasks in the queue, no matter what the setting
- *   is for the
- *   [task-level app_engine_routing][google.cloud.tasks.v2beta3.AppEngineHttpRequest.app_engine_routing].
- * The `url` that the task will be sent to is:
- * * `url =` [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] `+`
- *   [relative_uri][google.cloud.tasks.v2beta3.AppEngineHttpRequest.relative_uri]
- * Tasks can be dispatched to secure app handlers, unsecure app handlers, and
- * URIs restricted with
- * [`login:
- * admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
- * Because tasks are not run as any user, they cannot be dispatched to URIs
- * restricted with
- * [`login:
- * required`](https://cloud.google.com/appengine/docs/standard/python/config/appref)
- * Task dispatches also do not follow redirects.
- * The task attempt has succeeded if the app's request handler returns an HTTP
- * response code in the range [`200` - `299`]. The task attempt has failed if
- * the app's handler returns a non-2xx response code or Cloud Tasks does
- * not receive response before the [deadline][google.cloud.tasks.v2beta3.Task.dispatch_deadline]. Failed
- * tasks will be retried according to the
- * [retry configuration][google.cloud.tasks.v2beta3.Queue.retry_config]. `503` (Service Unavailable) is
- * considered an App Engine system error instead of an application error and
- * will cause Cloud Tasks' traffic congestion control to temporarily throttle
- * the queue's dispatches. Unlike other types of task targets, a `429` (Too Many
- * Requests) response from an app handler does not cause traffic congestion
- * control to throttle the queue.
- * </pre>

-   *
-   *
-   * <pre>
-   * App Engine HTTP request.
-   * The message defines the HTTP request that is sent to an App Engine app when
-   * the task is dispatched.
-   * Using [AppEngineHttpRequest][google.cloud.tasks.v2beta3.AppEngineHttpRequest] requires
-   * [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-api/access-control)
-   * Google IAM permission for the project
-   * and the following scope:
-   * `https://www.googleapis.com/auth/cloud-platform`
-   * The task will be delivered to the App Engine app which belongs to the same
-   * project as the queue. For more information, see
-   * [How Requests are
-   * Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-are-routed)
-   * and how routing is affected by
-   * [dispatch
-   * files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
-   * Traffic is encrypted during transport and never leaves Google datacenters.
-   * Because this traffic is carried over a communication mechanism internal to
-   * Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
-   * The request to the handler, however, will appear to have used the HTTP
-   * protocol.
-   * The [AppEngineRouting][google.cloud.tasks.v2beta3.AppEngineRouting] used to construct the URL that the task is
-   * delivered to can be set at the queue-level or task-level:
-   * * If set,
-   *   [app_engine_routing_override][google.cloud.tasks.v2beta3.AppEngineHttpQueue.app_engine_routing_override]
-   *   is used for all tasks in the queue, no matter what the setting
-   *   is for the
-   *   [task-level app_engine_routing][google.cloud.tasks.v2beta3.AppEngineHttpRequest.app_engine_routing].
-   * The `url` that the task will be sent to is:
-   * * `url =` [host][google.cloud.tasks.v2beta3.AppEngineRouting.host] `+`
-   *   [relative_uri][google.cloud.tasks.v2beta3.AppEngineHttpRequest.relative_uri]
-   * Tasks can be dispatched to secure app handlers, unsecure app handlers, and
-   * URIs restricted with
-   * [`login:
-   * admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
-   * Because tasks are not run as any user, they cannot be dispatched to URIs
-   * restricted with
-   * [`login:
-   * required`](https://cloud.google.com/appengine/docs/standard/python/config/appref)
-   * Task dispatches also do not follow redirects.
-   * The task attempt has succeeded if the app's request handler returns an HTTP
-   * response code in the range [`200` - `299`]. The task attempt has failed if
-   * the app's handler returns a non-2xx response code or Cloud Tasks does
-   * not receive response before the [deadline][google.cloud.tasks.v2beta3.Task.dispatch_deadline]. Failed
-   * tasks will be retried according to the
-   * [retry configuration][google.cloud.tasks.v2beta3.Queue.retry_config]. `503` (Service Unavailable) is
-   * considered an App Engine system error instead of an application error and
-   * will cause Cloud Tasks' traffic congestion control to temporarily throttle
-   * the queue's dispatches. Unlike other types of task targets, a `429` (Too Many
-   * Requests) response from an app handler does not cause traffic congestion
-   * control to throttle the queue.
-   * </pre>
-   *
-   * Protobuf type {@code google.cloud.tasks.v2beta3.AppEngineHttpRequest}

- * or the redirected worker acknowledges the task by returning a successful HTTP
- * response code ([`200` - `299`]), the task will be removed from the queue. If
- * any other HTTP response code is returned or no response is received, the
- * task will be retried according to the following:
- * * User-specified throttling: [retry configuration][google.cloud.tasks.v2beta3.Queue.retry_config],
- *   [rate limits][google.cloud.tasks.v2beta3.Queue.rate_limits], and the [queue's state][google.cloud.tasks.v2beta3.Queue.state].
- * * System throttling: To prevent the worker from overloading, Cloud Tasks may
- *   temporarily reduce the queue's effective rate. User-specified settings
- *   will not be changed.
- *  System throttling happens because:
- *   * Cloud Tasks backs off on all errors. Normally the backoff specified in
- *     [rate limits][google.cloud.tasks.v2beta3.Queue.rate_limits] will be used. But if the worker returns
- *     `429` (Too Many Requests), `503` (Service Unavailable), or the rate of
- *     errors is high, Cloud Tasks will use a higher backoff rate. The retry
- *     specified in the `Retry-After` HTTP response header is considered.
- *   * To prevent traffic spikes and to smooth sudden increases in traffic,
- *     dispatches ramp up slowly when the queue is newly created or idle and
- *     if large numbers of tasks suddenly become available to dispatch (due to
- *     spikes in create task rates, the queue being unpaused, or many tasks

-   * <pre>
-   * HTTP request.
-   * The task will be pushed to the worker as an HTTP request. If the worker
-   * or the redirected worker acknowledges the task by returning a successful HTTP
-   * response code ([`200` - `299`]), the task will be removed from the queue. If
-   * any other HTTP response code is returned or no response is received, the
-   * task will be retried according to the following:
-   * * User-specified throttling: [retry configuration][google.cloud.tasks.v2beta3.Queue.retry_config],
-   *   [rate limits][google.cloud.tasks.v2beta3.Queue.rate_limits], and the [queue's state][google.cloud.tasks.v2beta3.Queue.state].
-   * * System throttling: To prevent the worker from overloading, Cloud Tasks may
-   *   temporarily reduce the queue's effective rate. User-specified settings
-   *   will not be changed.
-   *  System throttling happens because:
-   *   * Cloud Tasks backs off on all errors. Normally the backoff specified in
-   *     [rate limits][google.cloud.tasks.v2beta3.Queue.rate_limits] will be used. But if the worker returns
-   *     `429` (Too Many Requests), `503` (Service Unavailable), or the rate of
-   *     errors is high, Cloud Tasks will use a higher backoff rate. The retry
-   *     specified in the `Retry-After` HTTP response header is considered.
-   *   * To prevent traffic spikes and to smooth sudden increases in traffic,
-   *     dispatches ramp up slowly when the queue is newly created or idle and
-   *     if large numbers of tasks suddenly become available to dispatch (due to
-   *     spikes in create task rates, the queue being unpaused, or many tasks
-   *     that are scheduled at the same time).

-//     specified in the `Retry-After` HTTP response header is considered.
-//
-//   * To prevent traffic spikes and to smooth sudden increases in traffic,
-//     dispatches ramp up slowly when the queue is newly created or idle and
-//     if large numbers of tasks suddenly become available to dispatch (due to
-//     spikes in create task rates, the queue being unpaused, or many tasks
