> BigQueryIO: update sink to shard into multiple write jobs
> ---------------------------------------------------------
>
> Key: BEAM-383
> URL: https://issues.apache.org/jira/browse/BEAM-383
> Project: Beam
> Issue Type: Bug
> Components: sdk-java-gcp
> Reporter: Daniel Halperin
> Assignee: Ian Zhou
>
> BigQuery has global limits on both the # files that can be written in a
> single job and the total bytes in those files. We should be able to modify
> BigQueryIO.Write to chunk into multiple smaller jobs that meet these limits,
> write to temp tables, and atomically copy into the destination table.
> This functionality will let us safely stay within BQ's load job limits.
