Class SubscriptionAdminClient

java.lang.Object
com.google.cloud.pubsub.v1.SubscriptionAdminClient
All Implemented Interfaces:
com.google.api.gax.core.BackgroundResource, AutoCloseable
@Generated("by gapic-generator-java") public class SubscriptionAdminClient extends Object implements com.google.api.gax.core.BackgroundResource
Service Description: The service that an application uses to manipulate subscriptions and to consume messages from a subscription via the `Pull` method or by establishing a bi-directional stream using the `StreamingPull` method.

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: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (SubscriptionAdminClient subscriptionAdminClient = SubscriptionAdminClient.create()) {
   SubscriptionName name = SubscriptionName.of("[PROJECT]", "[SUBSCRIPTION]");
   TopicName topic = TopicName.ofProjectTopicName("[PROJECT]", "[TOPIC]");
   PushConfig pushConfig = PushConfig.newBuilder().build();
   int ackDeadlineSeconds = 2135351438;
   Subscription response =
       subscriptionAdminClient.createSubscription(name, topic, pushConfig, ackDeadlineSeconds);
 }

Note: close() needs to be called on the SubscriptionAdminClient object to clean up resources such as threads. In the example above, try-with-resources is used, which automatically calls close().

Methods
Method Description Method Variants

CreateSubscription

Creates a subscription to a given topic. See the [resource name rules] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`.

If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • createSubscription(Subscription request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • createSubscription(SubscriptionName name, TopicName topic, PushConfig pushConfig, int ackDeadlineSeconds)

  • createSubscription(SubscriptionName name, String topic, PushConfig pushConfig, int ackDeadlineSeconds)

  • createSubscription(String name, TopicName topic, PushConfig pushConfig, int ackDeadlineSeconds)

  • createSubscription(String name, String topic, PushConfig pushConfig, int ackDeadlineSeconds)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • createSubscriptionCallable()

GetSubscription

Gets the configuration details of a subscription.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • getSubscription(GetSubscriptionRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • getSubscription(SubscriptionName subscription)

  • getSubscription(String subscription)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • getSubscriptionCallable()

UpdateSubscription

Updates an existing subscription by updating the fields specified in the update mask. Note that certain properties of a subscription, such as its topic, are not modifiable.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • updateSubscription(UpdateSubscriptionRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

  • updateSubscription(Subscription subscription, FieldMask updateMask)

  • listSubscriptionsPagedCallable()

  • listSubscriptionsCallable()

DeleteSubscription

Deletes an existing subscription. All messages retained in the subscription are immediately dropped. Calls to `Pull` after deletion will return `NOT_FOUND`. After a subscription is deleted, a new one may be created with the same name, but the new one has no association with the old subscription or its topic unless the same topic is specified.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • deleteSubscription(DeleteSubscriptionRequest request)

  • deleteSubscriptionCallable()

ModifyAckDeadline

Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level `ackDeadlineSeconds` used for subsequent messages.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • modifyAckDeadline(ModifyAckDeadlineRequest request)

"Flattened" method variants have converted the fields of the request object into function parameters to enable multiple ways to call the same method.

Acknowledge

Acknowledges the messages associated with the `ack_ids` in the `AcknowledgeRequest`. The Pub/Sub system can remove the relevant messages from the subscription.

Acknowledging a message whose ack deadline has expired may succeed, but such a message may be redelivered later. Acknowledging a message more than once will not result in an error.

  • pull(String subscription, int maxMessages)

  • pull(SubscriptionName subscription, boolean returnImmediately, int maxMessages)

  • pull(String subscription, boolean returnImmediately, int maxMessages)

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • pullCallable()

StreamingPull

Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgements and ack deadline modifications back to the server. The server will close the stream and return the status on any error. The server may close the stream with status `UNAVAILABLE` to reassign server-side resources, in which case, the client should re-establish the stream. Flow control can be achieved by configuring the underlying RPC channel.

Callable method variants take no parameters and return an immutable API callable object, which can be used to initiate calls to the service.

  • streamingPullCallable()

ModifyPushConfig

Modifies the `PushConfig` for a specified subscription.

This may be used to change a push subscription to a pull one (signified by an empty `PushConfig`) or vice versa, or change the endpoint URL and other attributes of a push subscription. Messages will accumulate for delivery continuously through the call regardless of changes to the `PushConfig`.

Request object method variants only take one parameter, a request object, which must be constructed before the call.

  • modifyPushConfig(ModifyPushConfigRequest request)

That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. If the snapshot already exists, returns `ALREADY_EXISTS`. If the requested subscription doesn't exist, returns `NOT_FOUND`. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned. See also the `Snapshot.expire_time` field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names).

See the individual methods for example code.

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.

This class can be customized by passing in a custom instance of SubscriptionAdminSettings to create(). For example:

To customize credentials: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SubscriptionAdminSettings subscriptionAdminSettings =
     SubscriptionAdminSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 SubscriptionAdminClient subscriptionAdminClient =
     SubscriptionAdminClient.create(subscriptionAdminSettings);

To customize the endpoint: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SubscriptionAdminSettings subscriptionAdminSettings =
     SubscriptionAdminSettings.newBuilder().setEndpoint(myEndpoint).build();
 SubscriptionAdminClient subscriptionAdminClient =
     SubscriptionAdminClient.create(subscriptionAdminSettings);

To use REST (HTTP1.1/JSON) transport (instead of gRPC) for sending and receiving requests over the wire: 


 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 SubscriptionAdminSettings subscriptionAdminSettings =
     SubscriptionAdminSettings.newHttpJsonBuilder().build();
 SubscriptionAdminClient subscriptionAdminClient =
     SubscriptionAdminClient.create(subscriptionAdminSettings);

      Creates a subscription to a given topic. See the [resource name rules] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`.

      If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

   int ackDeadlineSeconds = 2135351438;
   Subscription response =
       subscriptionAdminClient.createSubscription(name, topic, pushConfig, ackDeadlineSeconds);
 }
      Parameters:
      name - Required. The name of the subscription. It must have the format `"projects/{project}/subscriptions/{subscription}"`. `{subscription}` must start with a letter, and contain only letters (`[A-Za-z]`), numbers (`[0-9]`), dashes (`-`), underscores (`_`), periods (`.`), tildes (`~`), plus (`+`) or percent signs (`%`). It must be between 3 and 255 characters in length, and it must not start with `"goog"`.
      topic - Required. The name of the topic from which this subscription is receiving messages. Format is `projects/{project}/topics/{topic}`. The value of this field will be `_deleted-topic_` if the topic has been deleted.
      pushConfig - Optional. If push delivery is used with this subscription, this field is used to configure it.
      ackDeadlineSeconds - Optional. The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be _outstanding_. During that time period, the message will not be redelivered (on a best-effort basis).

      For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call `ModifyAckDeadline` with the corresponding `ack_id` if using non-streaming pull or send the `ack_id` in a `StreamingModifyAckDeadlineRequest` if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used.

      For push delivery, this value is also used to set the request timeout for the call to the push endpoint.

      If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

      Creates a subscription to a given topic. See the [resource name rules] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). If the subscription already exists, returns `ALREADY_EXISTS`. If the corresponding topic doesn't exist, returns `NOT_FOUND`.

      If the name is not provided in the request, the server will assign a random name for this subscription on the same project as the topic, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). The generated name is populated in the returned Subscription object. Note that for REST API requests, you must specify a name in the request.

      Sample code: 

      
 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (SubscriptionAdminClient subscriptionAdminClient = SubscriptionAdminClient.create()) {
   String name = SubscriptionName.of("[PROJECT]", "[SUBSCRIPTION]").toString();
   String topic = TopicName.ofProjectTopicName("[PROJECT]", "[TOPIC]").toString();
   PushConfig pushConfig = PushConfig.newBuilder().build();
   int ackDeadlineSeconds = 2135351438;
   Subscription response =
       subscriptionAdminClient.createSubscription(name, topic, pushConfig, ackDeadlineSeconds);
 }
      Parameters:
      name - Required. The name of the subscription. It must have the format `"projects/{project}/subscriptions/{subscription}"`. `{subscription}` must start with a letter, and contain only letters (`[A-Za-z]`), numbers (`[0-9]`), dashes (`-`), underscores (`_`), periods (`.`), tildes (`~`), plus (`+`) or percent signs (`%`). It must be between 3 and 255 characters in length, and it must not start with `"goog"`.
      topic - Required. The name of the topic from which this subscription is receiving messages. Format is `projects/{project}/topics/{topic}`. The value of this field will be `_deleted-topic_` if the topic has been deleted.
      pushConfig - Optional. If push delivery is used with this subscription, this field is used to configure it.
      ackDeadlineSeconds - Optional. The approximate amount of time (on a best-effort basis) Pub/Sub waits for the subscriber to acknowledge receipt before resending the message. In the interval after the message is delivered and before it is acknowledged, it is considered to be _outstanding_. During that time period, the message will not be redelivered (on a best-effort basis).

      For pull subscriptions, this value is used as the initial value for the ack deadline. To override this value for a given message, call `ModifyAckDeadline` with the corresponding `ack_id` if using non-streaming pull or send the `ack_id` in a `StreamingModifyAckDeadlineRequest` if using streaming pull. The minimum custom deadline you can specify is 10 seconds. The maximum custom deadline you can specify is 600 seconds (10 minutes). If this parameter is 0, a default value of 10 seconds is used.

      For push delivery, this value is also used to set the request timeout for the call to the push endpoint.

      If the subscriber never acknowledges the message, the Pub/Sub system will eventually redeliver the message.

      Throws:
      com.google.api.gax.rpc.ApiException - if the remote call fails

    • modifyAckDeadline

      public final void modifyAckDeadline(SubscriptionName subscription, List<String> ackIds, int ackDeadlineSeconds)
      Modifies the ack deadline for a specific message. This method is useful to indicate that more time is needed to process a message by the subscriber, or to make the message available for redelivery if the processing was interrupted. Note that this does not modify the subscription-level `ackDeadlineSeconds` used for subsequent messages.

      Sample code: 

      
 // This snippet has been automatically generated and should be regarded as a code template only.
 // It will require modifications to work:
 // - It may require correct/in-range values for request initialization.
 // - It may require specifying regional endpoints when creating the service client as shown in
 // https://cloud.google.com/java/docs/setup#configure_endpoints_for_the_client_library
 try (SubscriptionAdminClient subscriptionAdminClient = SubscriptionAdminClient.create()) {
   SubscriptionName subscription = SubscriptionName.of("[PROJECT]", "[SUBSCRIPTION]");
   List<String> ackIds = new ArrayList<>();
   int ackDeadlineSeconds = 2135351438;
   subscriptionAdminClient.modifyAckDeadline(subscription, ackIds, ackDeadlineSeconds);
 }
      Parameters:
      subscription - Required. The name of the subscription. Format is `projects/{project}/subscriptions/{sub}`.
      ackIds - Required. List of acknowledgment IDs.
      ackDeadlineSeconds - Required. The new ack deadline with respect to the time this request was sent to the Pub/Sub system. For example, if the value is 10, the new ack deadline will expire 10 seconds after the `ModifyAckDeadline` call was made. Specifying zero might immediately make the message available for delivery to another subscriber client. This typically results in an increase in the rate of message redeliveries (that is, duplicates). The minimum deadline you can specify is 0 seconds. The maximum deadline you can specify in a single request is 600 seconds (10 minutes).
      Throws:
      com.google.api.gax.rpc.ApiException - if the remote call fails

       subscriptionAdminClient.pull(subscription, returnImmediately, maxMessages);
 }
      Parameters:
      subscription - Required. The subscription from which messages should be pulled. Format is `projects/{project}/subscriptions/{sub}`.
      returnImmediately - Optional. If this field set to true, the system will respond immediately even if it there are no messages available to return in the `Pull` response. Otherwise, the system may wait (for a bounded amount of time) until at least one message is available, rather than returning no messages. Warning: setting this field to `true` is discouraged because it adversely impacts the performance of `Pull` operations. We recommend that users do not set this field.
      maxMessages - Required. The maximum number of messages to return for this request. Must be a positive integer. The Pub/Sub system may return fewer than the number specified.
      Throws:
      com.google.api.gax.rpc.ApiException - if the remote call fails

    • streamingPullCallable

      public final com.google.api.gax.rpc.BidiStreamingCallable<StreamingPullRequest,StreamingPullResponse> streamingPullCallable()
      Establishes a stream with the server, which sends messages down to the client. The client streams acknowledgements and ack deadline modifications back to the server. The server will close the stream and return the status on any error. The server may close the stream with status `UNAVAILABLE` to reassign server-side resources, in which case, the client should re-establish the stream. Flow control can be achieved by configuring the underlying RPC channel.

    • createSnapshot

      public final Snapshot createSnapshot(SnapshotName name, SubscriptionName subscription)
      Creates a snapshot from the requested subscription. Snapshots are used in [Seek](https://cloud.google.com/pubsub/docs/replay-overview) operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. If the snapshot already exists, returns `ALREADY_EXISTS`. If the requested subscription doesn't exist, returns `NOT_FOUND`. If the backlog in the subscription is too old -- and the resulting snapshot would expire in less than 1 hour -- then `FAILED_PRECONDITION` is returned. See also the `Snapshot.expire_time` field. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription, conforming to the [resource name format] (https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). The generated name is populated in the returned Snapshot object. Note that for REST API requests, you must specify a name in the request.

      Parameters:
      name - Required. User-provided name for this snapshot. If the name is not provided in the request, the server will assign a random name for this snapshot on the same project as the subscription. Note that for REST API requests, you must specify a name. See the [resource name rules](https://cloud.google.com/pubsub/docs/pubsub-basics#resource_names). Format is `projects/{project}/snapshots/{snap}`.
      subscription - Required. The subscription whose backlog the snapshot retains. Specifically, the created snapshot is guaranteed to retain: (a) The existing backlog on the subscription. More precisely, this is defined as the messages in the subscription's backlog that are unacknowledged upon the successful completion of the `CreateSnapshot` request; as well as: (b) Any messages published to the subscription's topic following the successful completion of the CreateSnapshot request.

    • deleteSnapshot

      public final void deleteSnapshot(DeleteSnapshotRequest request)
      Removes an existing snapshot. Snapshots are used in [Seek] (https://cloud.google.com/pubsub/docs/replay-overview) operations, which allow you to manage message acknowledgments in bulk. That is, you can set the acknowledgment state of messages in an existing subscription to the state captured by a snapshot. When the snapshot is deleted, all messages retained in the snapshot are immediately dropped. After a snapshot is deleted, a new one may be created with the same name, but the new one has no association with the old snapshot or its subscription, unless the same subscription is specified.
