Work Description: tvalentyn commented on issue #11086: [BEAM-8910] Make
custom BQ source read from Avro
URL: https://github.com/apache/beam/pull/11086#issuecomment-597911424
> * For bytes, AvroSource is currently returning base64 encoded bytes. I am
trying to figure out how to handle this. For py2, strings and bytes may not be
differentiable, so we may not be able to handle this properly...
Do you have a summary of Py2 vs Py3 x Current Behavior vs New behavior?
What is returned on Py3 - is it also base64 encoded bytes?
This is a prior discussion on Py3 migration issues in Bigquery:

It took us some time to understand what was going on

> The proposed BigQuery bounded source in Python SDK (see PR:
> [https://github.com/apache/beam/pull/9772)] uses a BigQuery export job to
> take a snapshot of the table and read from each produced JSON file. A
> performance improvement can be gain by switching to AVRO instead.
