Methods

Acknowledge(AcknowledgeRequest, CallOptions)

public virtual Empty Acknowledge(AcknowledgeRequest request, CallOptions options)

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.

Parameters
Name	Description
request	AcknowledgeRequest The request to send to the server.
options	CallOptions The options for the call.

Returns
Type	Description
Empty	The response received from the server.

Acknowledge(AcknowledgeRequest, Metadata, DateTime?, CancellationToken)

public virtual Empty Acknowledge(AcknowledgeRequest request, Metadata headers = null, DateTime? deadline = null, CancellationToken cancellationToken = default)

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.

Parameters
Name	Description
request	AcknowledgeRequest The request to send to the server.
headers	Metadata The initial metadata to send with the call. This parameter is optional.
deadline	DateTime An optional deadline for the call. The call will be cancelled if deadline is hit.
cancellationToken	CancellationToken An optional token for canceling the call.

Returns
Type	Description
Empty	The response received from the server.

CreateSnapshot(CreateSnapshotRequest, CallOptions)

public virtual Snapshot CreateSnapshot(CreateSnapshotRequest request, CallOptions options)

Creates a snapshot from the requested subscription. Snapshots are used in Seek 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. 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	Description
request	CreateSnapshotRequest The request to send to the server.
options	CallOptions The options for the call.

ModifyAckDeadlineAsync(ModifyAckDeadlineRequest, Metadata, DateTime?, CancellationToken)

public virtual AsyncUnaryCall<Empty> ModifyAckDeadlineAsync(ModifyAckDeadlineRequest request, Metadata headers = null, DateTime? deadline = null, CancellationToken cancellationToken = default)

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.

Parameters
Name	Description
request	ModifyAckDeadlineRequest The request to send to the server.
headers	Metadata The initial metadata to send with the call. This parameter is optional.
deadline	DateTime An optional deadline for the call. The call will be cancelled if deadline is hit.
cancellationToken	CancellationToken An optional token for canceling the call.

Returns
Type	Description
AsyncUnaryCallEmpty	The call object.
