Cloud Bigtable V2 Client - Class ReadRowsResponse (1.31.1)

Reference documentation and code samples for the Cloud Bigtable V2 Client class ReadRowsResponse.

Response message for Bigtable.ReadRows.

Generated from protobuf message google.bigtable.v2.ReadRowsResponse

Namespace

Google \ Cloud \ Bigtable \ V2

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.

↳ chunks array<Google\Cloud\Bigtable\V2\ReadRowsResponse\CellChunk>

A collection of a row's contents as part of the read request.

↳ last_scanned_row_key string

Optionally the server might return the row key of the last row it has scanned. The client can use this to construct a more efficient retry request if needed: any row keys or portions of ranges less than this row key can be dropped from the request. This is primarily useful for cases where the server has read a lot of data that was filtered out since the last committed row key, allowing the client to skip that work on a retry.

↳ request_stats Google\Cloud\Bigtable\V2\RequestStats

If requested, provide enhanced query performance statistics. The semantics dictate: * request_stats is empty on every (streamed) response, except * request_stats has non-empty information after all chunks have been streamed, where the ReadRowsResponse message only contains request_stats. * For example, if a read request would have returned an empty response instead a single ReadRowsResponse is streamed with empty chunks and request_stats filled. Visually, response messages will stream as follows: ... -> {chunks: [...]} -> {chunks: [], request_stats: {...}} __/ __/ Primary response Trailer of RequestStats info Or if the read did not return any values: {chunks: [], request_stats: {...}} __/ Trailer of RequestStats info
