Work Description: ryan-williams commented on issue #5862: [BEAM-2810]
fastavro integration test
URL: https://github.com/apache/beam/pull/5862#issuecomment-405097482
The previous PostCommit run had my fastavro IT time out, so I dropped the
default number of records from 10MM to 1MM, and now it passes.
That seems fine to me, though it would be nice if we could see/track the
timings of the {avro,fastavro} stages, to verify/demonstrate the speed
difference… not sure if the IT machinery gives us that for free or whether I'd
have to do something else to get it.
Either way, having it verify correctness is a win; thanks for the review!

> 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)
