Description

Current implementation of StreamingWriteFn(https://github.com/apache/beam/blob/c2f0d282337f3ae0196a7717712396a5a41fdde1/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/StreamingWriteFn.java#L102) sets insertId from input element, which is added an uniqueId by https://github.com/apache/beam/blob/c2f0d282337f3ae0196a7717712396a5a41fdde1/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TagWithUniqueIds.java#L53. Users report that if leaving insertId as empty, writing will be extremely speeded up. Can we add an bqOption like, nonInsertId and emit empty id based on this option?
