Request body

The request body contains data with the following structure:

JSON representation
{ "streamId": string, "writes": [ { object(Write) } ], "streamToken": string, "labels": { string: string, ... } }

Fields
streamId	string The ID of the write stream to resume. This may only be set in the first message. When left empty, a new write stream will be created.
writes[]	object(Write) The writes to apply. Always executed atomically and in order. This must be empty on the first request. This may be empty on the last request. This must not be empty on all other requests.
streamToken	string (bytes format) A stream token that was previously sent by the server. The client should set this field to the token from the most recent WriteResponse it has received. This acknowledges that the client has received responses up to this token. After sending this token, earlier tokens may not be used anymore. The server may close the stream if there are too many unacknowledged responses. Leave this field unset when creating a new stream. To resume a stream at a specific point, set this field and the streamId field. Leave this field unset when creating a new stream. A base64-encoded string.
labels	map (key: string, value: string) Labels associated with this write request. An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

streamToken	string (bytes format) A token that represents the position of this response in the stream. This can be used by a client to resume the stream at this point. This field is always set. A base64-encoded string.
writeResults[]	object(WriteResult) The result of applying the writes. This i-th write result corresponds to the i-th write in the request.
