Jakob Homan commented on PIG-3015:
----------------------------------
bq. Serious question: is there a reason to put this in Pig rather than keep
elsewhere, where you can iterate without being tied to Pig's release cycle?
Having tried that with the Avro Serde/Haivvreo, I'd say the code is better
treated as part of Hive since it's wasn't getting the correct amount of
attention it deserved in github. There's a definite cost to keeping the
components in sync, but there's a strong benefit to making it easy for people
to interact with Avro through Pig right out of the box.

> The current AvroStorage implementation has a lot of issues: it requires old
> versions of Avro, it copies data much more than needed, and it's verbose and
> complicated. (One pet peeve of mine is that old versions of Avro don't
> support Snappy compression.)
> I rewrote AvroStorage from scratch to fix these issues. In early tests, the
> new implementation is significantly faster, and the code is a lot simpler.
> Rewriting AvroStorage also enabled me to implement support for Trevni (as
> TrevniStorage).
> I'm opening this ticket to facilitate discussion while I figure out the best
> way to contribute the changes back to Apache.
