Work Description: kamilwu commented on issue #9772: [BEAM-1440] Create a
BigQuery source that implements iobase.BoundedSource for Python
URL: https://github.com/apache/beam/pull/9772#issuecomment-562605478
Thanks @robertwb for your comments!
> Why does this not work on the direct runners. Is it an issue of needing to
be split first?
Yes. I've already created a jira for this:
https://issues.apache.org/jira/browse/BEAM-8528
> would it make sense to implement this as an SDF instead?
My first attempt was a regular (non splittable) DoFn that triggers export
job followed by `MatchAll` and `ReadMatches` transforms. This worked, but I had
troubles with implementing the rest: waiting for query job, waiting for export
job and removing json files after reading. Using Source API turned out to be
simpler.

> 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].
