Joseph Adler updated PIG-3015:
------------------------------
Description:
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.
