>             Project: Beam
>          Issue Type: Bug
>          Components: io-java-gcp
>    Affects Versions: 2.25.0
>            Reporter: Kenneth Jung
>            Assignee: Vachan Shetty
>            Priority: P2

> 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).
