Reference documentation and code samples for the Google BigQuery Storage V1 Client class ReadRowsResponse.

Response from calling ReadRows may include row data, progress and throttling information.

Generated from protobuf message google.cloud.bigquery.storage.v1.ReadRowsResponse

Namespace

Methods

__construct

Constructor.

Parameters
Name Description
data array

Optional. Data for populating the Message object.
↳ avro_rows AvroRows

Serialized row data in AVRO format.
↳ arrow_record_batch ArrowRecordBatch

Serialized row data in Arrow RecordBatch format.
↳ row_count int|string

Number of serialized rows in the rows block.
↳ stats StreamStats

Statistics for the stream.
↳ throttle_state ThrottleState

Throttling state. If unset, the latest response still describes the current throttling status.
↳ avro_schema AvroSchema

Output only. Avro schema.
↳ arrow_schema ArrowSchema

Output only. Arrow schema.
↳ uncompressed_byte_size int|string

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.

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.

Returns
Type Description
