Overview

Request for the StreamingPull streaming RPC method. This request is used to establish the initial stream as well as to stream acknowledgements and ack deadline modifications from the client to the server.

Instance Attribute Details

#ack_ids ⇒ ::Array<::String>

Returns Optional. List of acknowledgement IDs for acknowledging previously received messages (received on this stream or a different stream). If an ack ID has expired, the corresponding message may be redelivered later. Acknowledging a message more than once will not result in an error. If the acknowledgement ID is malformed, the stream will be aborted with status INVALID_ARGUMENT.

Returns:

  • (::Array<::String>) —

#client_id ⇒ ::String

Returns Optional. A unique identifier that is used to distinguish client instances from each other. Only needs to be provided on the initial request. When a stream disconnects and reconnects for the same stream, the client_id should be set to the same value so that state associated with the old stream can be transferred to the new stream. The same client_id should not be used for different client instances.

#max_outstanding_bytes ⇒ ::Integer

Returns Optional. Flow control settings for the maximum number of outstanding bytes. When there are max_outstanding_bytes or more worth of messages currently sent to the streaming pull client that have not yet been acked or nacked, the server will stop sending more messages. The sending of messages resumes once the number of outstanding bytes is less than this value. If the value is <= 0, there is no limit to the number of outstanding bytes. This property can only be set on the initial StreamingPullRequest. If it is set on a subsequent request, the stream will be aborted with status INVALID_ARGUMENT.

#modify_deadline_ack_ids ⇒ ::Array<::String>

Returns Optional. List of acknowledgement IDs whose deadline will be modified based on the corresponding element in modify_deadline_seconds. This field can be used 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.

#modify_deadline_seconds ⇒ ::Array<::Integer>

Returns Optional. The list of new ack deadlines for the IDs listed in modify_deadline_ack_ids. The size of this list must be the same as the size of modify_deadline_ack_ids. If it differs the stream will be aborted with INVALID_ARGUMENT. Each element in this list is applied to the element in the same position in modify_deadline_ack_ids. The new ack deadline is with respect to the time this request was sent to the Pub/Sub system. Must be >= 0. For example, if the value is 10, the new ack deadline will expire 10 seconds after this request is received. If the value is 0, the message is immediately made available for another streaming or non-streaming pull request. If the value is < 0 (an error), the stream will be aborted with status INVALID_ARGUMENT.

#stream_ack_deadline_seconds ⇒ ::Integer

Returns Required. The ack deadline to use for the stream. This must be provided in the first request on the stream, but it can also be updated on subsequent requests from client to server. The minimum deadline you can specify is 10 seconds. The maximum deadline you can specify is 600 seconds (10 minutes).
