Subject [jira] [Commented] (PIG-3015) Rewrite of AvroStorage
Date Wed, 07 Nov 2012 20:35:11 GMT

    [ https://issues.apache.org/jira/browse/PIG-3015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13492680#comment-13492680
] 

Russell Jurney commented on PIG-3015:
-------------------------------------

I agree that we should replace the old AvroStorage with this one, and that we should make
AvroStorage a builtin.

However, I don't think its acceptable to break backwards-compatibility with the existing AvroStorage,
and having two implementations at once seems confusing. It would be best to extend this implementation
with those features required to maintain compatibility with the Piggybank AvroStorage before
committing it as a builtin.

It sounds like you're on top of this, Joe and Chelsoo :) I'll be a tester.

> 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.
> I'm opening this ticket to facilitate discussion while I figure out the best way to contribute
the changes back to Apache.
