Work Description: ryan-williams opened a new pull request #5496: do not
merge! [BEAM-2810] use fastavro in Avro IO
URL: https://github.com/apache/beam/pull/5496
Use [fastavro](https://github.com/tebeka/fastavro) for python Avro IO
instead of apache/avro; it is seemingly ≈10x faster.
Not ready for merging yet because it uses [a fork of fastavro that I
published to
test.pypi.org](https://test.pypi.org/project/fastavro-blocks/0.19.5.4/) (see
discussion at https://github.com/tebeka/fastavro/pull/208); I'd like to get CI
to run on it and allow folks to comment though.

> 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)
