----------------------------------------
Summary: Create a BigQuery source (that implements
iobase.BoundedSource) for Python SDK
Key: BEAM-1440
URL: https://issues.apache.org/jira/browse/BEAM-1440
Project: Beam
Issue Type: New Feature
Components: sdk-py
Reporter: Chamikara Jayalath
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].
