--------------------------------------
Summary: BigQuery bounded source does not work on DirectRunner
Key: BEAM-8528
URL: https://issues.apache.org/jira/browse/BEAM-8528
Project: Beam
Issue Type: Bug
Components: sdk-py-core
Reporter: Kamil Wasilewski
{code:java}
File "/home/Kamil/projects/beam/sdks/python/apache_beam/io/gcp/bigquery.py",
line 639, in get_range_tracker
raise NotImplementedError('BigQuery source must be split before being read')
NotImplementedError: BigQuery source must be split before being read
{code}
_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:

It seems that DataflowRunner and Flink are able to catch these exceptions
somehow, while DirectRunner is not.
