Class AdminServiceClient (1.14.7)

GitHub RepositoryProduct Reference

Service Description: The service that a client application uses to manage topics and subscriptions, such creating, listing, and deleting topics and subscriptions.

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 (AdminServiceClient adminServiceClient = AdminServiceClient.create()) {
   LocationName parent = LocationName.of("[PROJECT]", "[LOCATION]");
   Topic topic = Topic.newBuilder().build();
   String topicId = "topicId-1139259734";
   Topic response = adminServiceClient.createTopic(parent, topic, topicId);
 }

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

SeekSubscription

Performs an out-of-band seek for a subscription to a specified target, which may be timestamps or named positions within the message backlog. Seek translates these targets to cursors for each partition and orchestrates subscribers to start consuming messages from these seek cursors.

If an operation is returned, the seek has been registered and subscribers will eventually receive messages from the seek cursors (i.e. eventual consistency), as long as they are using a minimum supported client library version and not a system that tracks cursors independently of Pub/Sub Lite (e.g. Apache Beam, Dataflow, Spark). The seek operation will fail for unsupported clients.

If clients would like to know when subscribers react to the seek (or not), they can poll the operation. The seek operation will succeed and complete once subscribers are ready to receive messages from the seek cursors for all partitions of the topic. This means that the seek operation will not complete until all subscribers come online.

If the previous seek operation has not yet completed, it will be aborted and the new invocation of seek will supersede it.

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 AdminServiceSettings 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
 AdminServiceSettings adminServiceSettings =
     AdminServiceSettings.newBuilder()
         .setCredentialsProvider(FixedCredentialsProvider.create(myCredentials))
         .build();
 AdminServiceClient adminServiceClient = AdminServiceClient.create(adminServiceSettings);

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
 AdminServiceSettings adminServiceSettings =
     AdminServiceSettings.newBuilder().setEndpoint(myEndpoint).build();
 AdminServiceClient adminServiceClient = AdminServiceClient.create(adminServiceSettings);

seekSubscriptionAsync(SeekSubscriptionRequest request)

public final OperationFuture<SeekSubscriptionResponse,OperationMetadata> seekSubscriptionAsync(SeekSubscriptionRequest request)

Performs an out-of-band seek for a subscription to a specified target, which may be timestamps or named positions within the message backlog. Seek translates these targets to cursors for each partition and orchestrates subscribers to start consuming messages from these seek cursors.

If an operation is returned, the seek has been registered and subscribers will eventually receive messages from the seek cursors (i.e. eventual consistency), as long as they are using a minimum supported client library version and not a system that tracks cursors independently of Pub/Sub Lite (e.g. Apache Beam, Dataflow, Spark). The seek operation will fail for unsupported clients.

If clients would like to know when subscribers react to the seek (or not), they can poll the operation. The seek operation will succeed and complete once subscribers are ready to receive messages from the seek cursors for all partitions of the topic. This means that the seek operation will not complete until all subscribers come online.

If the previous seek operation has not yet completed, it will be aborted and the new invocation of seek will supersede it.

seekSubscriptionOperationCallable()

public final OperationCallable<SeekSubscriptionRequest,SeekSubscriptionResponse,OperationMetadata> seekSubscriptionOperationCallable()

Performs an out-of-band seek for a subscription to a specified target, which may be timestamps or named positions within the message backlog. Seek translates these targets to cursors for each partition and orchestrates subscribers to start consuming messages from these seek cursors.

If an operation is returned, the seek has been registered and subscribers will eventually receive messages from the seek cursors (i.e. eventual consistency), as long as they are using a minimum supported client library version and not a system that tracks cursors independently of Pub/Sub Lite (e.g. Apache Beam, Dataflow, Spark). The seek operation will fail for unsupported clients.

If clients would like to know when subscribers react to the seek (or not), they can poll the operation. The seek operation will succeed and complete once subscribers are ready to receive messages from the seek cursors for all partitions of the topic. This means that the seek operation will not complete until all subscribers come online.

If the previous seek operation has not yet completed, it will be aborted and the new invocation of seek will supersede it.
