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

Specifies a piece of a row's contents returned as part of the read response stream.

Generated from protobuf message google.bigtable.v2.ReadRowsResponse.CellChunk

Namespace

Methods

__construct

Constructor.

Parameters
Name	Description
data	array Optional. Data for populating the Message object.
↳ row_key	string The row key for this chunk of data. If the row key is empty, this CellChunk is a continuation of the same row as the previous CellChunk in the response stream, even if that CellChunk was in a previous ReadRowsResponse message.
↳ family_name	Google\Protobuf\StringValue The column family name for this chunk of data. If this message is not present this CellChunk is a continuation of the same column family as the previous CellChunk. The empty string can occur as a column family name in a response so clients must check explicitly for the presence of this message, not just for family_name.value being non-empty.
↳ qualifier	Google\Protobuf\BytesValue The column qualifier for this chunk of data. If this message is not present, this CellChunk is a continuation of the same column as the previous CellChunk. Column qualifiers may be empty so clients must check for the presence of this message, not just for qualifier.value being non-empty.
↳ timestamp_micros	int|string The cell's stored timestamp, which also uniquely identifies it within its column. Values are always expressed in microseconds, but individual tables may set a coarser granularity to further restrict the allowed values. For example, a table which specifies millisecond granularity will only allow values of timestamp_micros which are multiples of 1000. Timestamps are only set in the first CellChunk per cell (for cells split into multiple chunks).
↳ labels	array Labels applied to the cell by a RowFilter. Labels are only set on the first CellChunk per cell.
↳ value	string The value stored in the cell. Cell values can be split across multiple CellChunks. In that case only the value field will be set in CellChunks after the first: the timestamp and labels will only be present in the first CellChunk, even if the first CellChunk came in a previous ReadRowsResponse.
↳ value_size	int If this CellChunk is part of a chunked cell value and this is not the final chunk of that cell, value_size will be set to the total length of the cell value. The client can use this size to pre-allocate memory to hold the full cell value.
↳ reset_row	bool Indicates that the client should drop all previous chunks for row_key, as it will be re-read from the beginning.
↳ commit_row	bool Indicates that the client can safely process all previous chunks for row_key, as its data has been fully read.

getRowKey

setFamilyNameValue

Sets the field by wrapping a primitive type in a Google\Protobuf\StringValue object.
