Ning Kang created BEAM-11705: -------------------------------- Summary: Write to bigquery always assigns unique insert id per row causing performance issue Key: BEAM-11705 URL: https://issues.apache.org/jira/browse/BEAM-11705 Project: Beam Issue Type: Improvement Components: io-py-gcp Reporter: Ning Kang
The `ignore_insert_id` argument in BigQuery IO Connector https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/gcp/bigquery.py#L1471 does not take effect. Because the implementation of sending insert rows request always uses an auto generated uuid even when the insert_ids is set to None when `ignore_insert_id` is False: https://github.com/apache/beam/blob/master/sdks/python/apache_beam/io/gcp/bigquery_tools.py#L1062 The implementation should explicitly set insert_id as None instead of using a generated uuid, an example: https://github.com/googleapis/python-bigquery/blob/master/samples/table_insert_rows_explicit_none_insert_ids.py#L33 An unique insert id per row would make the streaming inserts very slow. -- This message was sent by Atlassian Jira (v8.3.4#803005)
