----------------------------------------------
Hi [~chamikara],
This feature is important for the project I'm working on (almost a blocker) to
be able to support dynamic queries through template arguments in Python. I'm
experienced in Python and I've being using BigQuery for some months now, so I
would like to contribute. How should I proceed?
I've contributed to other big open source projects in the past (Openstack) and
the process to contribute was very rigid (getting blueprints approved
beforehand, etc.) so I just want to check I'm doing it right before coding.

> Key: BEAM-1440
> URL: https://issues.apache.org/jira/browse/BEAM-1440
> Project: Beam
> Issue Type: New Feature
> Components: sdk-py-core
> Reporter: Chamikara Jayalath
> Priority: Major
>
> 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].
