Cheolsoo Park updated PIG-3015:
-------------------------------
Attachment: PIG-3015-7.patch
[~jadler], thank you for the update. I just made very minor changes to the
patch as follows:
* Took out PIG-2266 and posted it in a separate patch in PIG-2266. I will
commit it after running tests.
* Parameterized the snappy version in build.xml and ivy.xml.
* Down-graded Avro version to 1.7.3. I noticed that you bumped it to
1.7.4-SNAPSHOT, but when I tried your patch, 1.7.4-SNAPSHOT didn't exist on the
Maven repo. Did you want Avro 1.7.4-SNAPSHOT because of recent updates in Avro?

> 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.
