Johannes Schwenk commented on PIG-3015:
---------------------------------------
First of all I want to say many thanks Joseph, for all the great work on this
so far! This will be very useful for my work.
By the way: You certainly know of PIG-2684 about the existing AvroStorage
implementation havin problems with <code><alias_name>::</code> prefix that is
added by pigs join operations? What is your solution to this issue in the new
implementation?
> Rewrite of AvroStorage

> Key: PIG-3015
> URL: https://issues.apache.org/jira/browse/PIG-3015

> 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.
