getUncompressedByteSize()

public long getUncompressedByteSize()

Optional. If the row data in this ReadRowsResponse is compressed, then uncompressed byte size is the original size of the uncompressed row data. If it is set to a value greater than 0, then decompress into a buffer of size uncompressed_byte_size using the compression codec that was requested during session creation time and which is specified in TableReadOptions.response_compression_codec in ReadSession. This value is not set if no response_compression_codec was not requested and it is -1 if the requested compression would not have reduced the size of this ReadRowsResponse's row data. This attempts to match Apache Arrow's behavior described here https://github.com/apache/arrow/issues/15102 where the uncompressed length may be set to -1 to indicate that the data that follows is not compressed, which can be useful for cases where compression does not yield appreciable savings. When uncompressed_byte_size is not greater than 0, the client should skip decompression.

optional int64 uncompressed_byte_size = 9 [(.google.api.field_behavior) = OPTIONAL];

Returns
Type Description
long

The uncompressedByteSize.
