---------------------------------------

[~robertwb] [~altay] is there a best point of contact for Python direct runner bug reports?

> _get_range_tracker_ and _read_ methods aren't implemented in __BigQuerySource_. This is purposeful — the runner is expected to call _split_ instead. The Java implementation works the same way: [link|https://github.com/apache/beam/blob/c2f0d282337f3ae0196a7717712396a5a41fdde1/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQuerySourceBase.java]
> It seems that DataflowRunner and Flink are able to catch these exceptions somehow, while DirectRunner is not.
