Work Description: kamilwu commented on pull request #9772: [BEAM-1440] Create a BigQuery source that implements iobase.BoundedSource for Python
URL: https://github.com/apache/beam/pull/9772
This is an implementation of a BigQuery source that implements iobase.BoundedSource interface.
It works the same way as in Java SDK, which means that it exports BigQuery table to JSON and returns TextSource objects in the split() call.
What's not done yet:
* Removing exported JSON files after successful read
Please also do note that the source does not currently work with DirectRunner.

> Currently we have a BigQuery native source for Python SDK [1].
> This can only be used by Dataflow runner.
> We should implement a Beam BigQuery source that implements iobase.BoundedSource [2] interface so that other runners that try to use Python SDK can read from BigQuery as well. Java SDK already has a Beam BigQuery source [3].
