Properties
AckIds
public RepeatedField<string> AckIds { get; }
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
.

RepeatedFieldstring |
ClientId
public string ClientId { get; set; }
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.

string |
MaxOutstandingBytes
public long MaxOutstandingBytes { get; set; }
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
.

MaxOutstandingMessages
public long MaxOutstandingMessages { get; set; }
Flow control settings for the maximum number of outstanding messages. When
there are max_outstanding_messages
or more currently sent to the
streaming pull client that have not yet been acked or nacked, the server
stops sending more messages. The sending of messages resumes once the
number of outstanding messages is less than this value. If the value is
<= 0, there is no limit to the number of outstanding messages. 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
.

ModifyDeadlineAckIds
public RepeatedField<string> ModifyDeadlineAckIds { get; }
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.

Type | Description |
RepeatedFieldstring |
ModifyDeadlineSeconds
public RepeatedField<int> ModifyDeadlineSeconds { get; }
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
.
