Review comment:
Just use _create_avro_source and _create_avro_sink from tests instead of "as
Avro..." ? I think that is cleaner.

> Seems like this job is reading Avro files (exported by BigQuery) at about 2
> MB/s.
> We use the standard Python "avro" library which is apparently known to be
> very slow (10x+ slower than Java)
> http://apache-avro.679487.n3.nabble.com/Avro-decode-very-slow-in-Python-td4034422.html,
> and there are alternatives e.g. https://pypi.python.org/pypi/fastavro/
