> Key: BEAM-11208
> URL: https://issues.apache.org/jira/browse/BEAM-11208
> Project: Beam
> Issue Type: Bug
> Components: io-java-gcp
> Affects Versions: 2.25.0
> Reporter: Kenneth Jung
> Assignee: Vachan Shetty
> Priority: P2
> Original Estimate: 168h
> Time Spent: 0.5h
> Remaining Estimate: 167.5h

> The BigQueryStorageStreamSource attempts to call
> [SplitReadStream](https://cloud.google.com/bigquery/docs/reference/storage/rpc/google.cloud.bigquery.storage.v1#bigqueryread)
> for each splitAtFraction call. However, the storage API
> [limits](https://cloud.google.com/bigquery/quotas#storage-limits) the number
> of control plane operations per minute for a given project, which can lead to
> the service being overloaded in the event of a large pipeline. The stream
> reader should not attempt to split a stream once it has learned that the
> stream can no longer be split (e.g. once a SplitReadStream call returns an
> empty response).
