> Key: BEAM-2864
> URL: https://issues.apache.org/jira/browse/BEAM-2864
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Reporter: Eugene Kirpichov
> Priority: P2
> Labels: stale-P2
>
> See https://github.com/GoogleCloudPlatform/DataflowJavaSDK/issues/603
> motivated by SO question
> https://stackoverflow.com/questions/46076914/apache-beam-update-bigquery-table-row-with-bigqueryio
> Perhaps one way we can do this is make BigQueryIO return a PValue that can be
> sequenced with other things, and implement a BigQuery.update() transform that
> executes a single DML statement (or a small collection thereof - since DML in
> BigQuery is very scarce), and let the user sandwich them together if they
> would like to.
