Class AdminServiceClient (2.26.0)

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

Equality

Instances of this class created via copy-construction or copy-assignment always compare equal. Instances created with equal std::shared_ptr<*Connection> objects compare equal. Objects that compare equal share the same underlying resources.

Performance

Creating a new instance of this class is a relatively expensive operation, new objects establish new connections to the service. In contrast, copy-construction, move-construction, and the corresponding assignment operations are relatively efficient as the copies share all underlying resources.

Thread Safety

Concurrent access to different instances of this class, even if they compare equal, is guaranteed to work. Two or more threads operating on the same instance of this class is not guaranteed to work. Since copy-construction and move-construction is a relatively efficient operation, consider using such a copy when using this class from multiple threads.

SeekSubscription(google::cloud::pubsublite::v1::SeekSubscriptionRequest const &, Options)

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.

Parameters
Name	Description
`request`	`google::cloud::pubsublite::v1::SeekSubscriptionRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.pubsublite.v1.SeekSubscriptionRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.

Returns

Type Description

future< StatusOr< google::cloud::pubsublite::v1::SeekSubscriptionResponse > >

A future that becomes satisfied when the LRO (Long Running Operation) completes or the polling policy in effect for this call is exhausted. The future is satisfied with an error if the LRO completes with an error or the polling policy is exhausted. In this case the StatusOr returned by the future contains the error. If the LRO completes successfully the value of the future contains the LRO's result. For this RPC the result is a google.cloud.pubsublite.v1.SeekSubscriptionResponse proto message. The C++ class representing this message is created by Protobuf, using the Protobuf mapping rules.

SeekSubscription(ExperimentalTag, NoAwaitTag, google::cloud::pubsublite::v1::SeekSubscriptionRequest const &, Options)

Performs an out-of-band seek for a subscription to a specified target, which may be timestamps or named positions within the message backlog.

`StatusOr< google::cloud::pubsublite::v1::Reservation >`	the result of the RPC. The response message type (google.cloud.pubsublite.v1.Reservation) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

UpdateReservation(google::cloud::pubsublite::v1::UpdateReservationRequest const &, Options)

Updates properties of the specified reservation.

Parameters
Name	Description
`request`	`google::cloud::pubsublite::v1::UpdateReservationRequest const &` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.pubsublite.v1.UpdateReservationRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`StatusOr< google::cloud::pubsublite::v1::Reservation >`	the result of the RPC. The response message type (google.cloud.pubsublite.v1.Reservation) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

DeleteReservation(std::string const &, Options)

Deletes the specified reservation.

Parameters
Name	Description
`name`	`std::string const &` Required. The name of the reservation to delete. Structured like: projects/{project_number}/locations/{location}/reservations/{reservation_id}
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`Status`	a `Status` object. If the request failed, the status contains the details of the failure.

DeleteReservation(google::cloud::pubsublite::v1::DeleteReservationRequest const &, Options)

Deletes the specified reservation.

Parameters
Name	Description

In this case, the proto message is a google.cloud.pubsublite.v1.DeleteReservationRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`Status`	a `Status` object. If the request failed, the status contains the details of the failure.

ListReservationTopics(std::string const &, Options)

Lists the topics attached to the specified reservation.

Parameters
Name	Description
`name`	`std::string const &` Required. The name of the reservation whose topics to list. Structured like: projects/{project_number}/locations/{location}/reservations/{reservation_id}
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< std::string >

ListReservationTopics(google::cloud::pubsublite::v1::ListReservationTopicsRequest, Options)

Lists the topics attached to the specified reservation.

Parameters
Name	Description
`request`	`google::cloud::pubsublite::v1::ListReservationTopicsRequest` Unary RPCs, such as the one wrapped by this function, receive a single `request` proto message which includes all the inputs for the RPC. In this case, the proto message is a google.cloud.pubsublite.v1.ListReservationTopicsRequest. Proto messages are converted to C++ classes by Protobuf, using the Protobuf mapping rules.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns

Type Description

StreamRange< std::string >

AsyncGetTopicPartitions(std::string const &, Options)

Returns the partition information for the requested topic.

Parameters
Name	Description
`name`	`std::string const &` Required. The topic whose partition information to return.
`opts`	`Options` Optional. Override the class-level options, such as retry and backoff policies.

Returns
Type	Description
`future< StatusOr< google::cloud::pubsublite::v1::TopicPartitions > >`	the result of the RPC. The response message type (google.cloud.pubsublite.v1.TopicPartitions) is mapped to a C++ class using the Protobuf mapping rules. If the request fails, the `StatusOr` contains the error details.

AsyncGetTopicPartitions(google::cloud::pubsublite::v1::GetTopicPartitionsRequest const &, Options)

Returns the partition information for the requested topic.

Parameters
Name	Description
