final case class CellChunk(rowKey: ByteString, familyName: Option[String], qualifier: Option[ByteString], timestampMicros: Long, labels: Seq[String], value: ByteString, valueSize: Int, rowStatus: RowStatus, unknownFields: UnknownFieldSet) extends GeneratedMessage, Updatable[CellChunk]

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

Value parameters

familyName: 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.
labels: Labels applied to the cell by a [RowFilter][google.bigtable.v2.RowFilter]. Labels are only set on the first CellChunk per cell.
qualifier: 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.
rowKey: 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.
timestampMicros: 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).
value: 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.
valueSize: 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.
