Subject [jira] [Commented] (PIG-3015) Rewrite of AvroStorage
Date Tue, 20 Nov 2012 18:00:58 GMT

    [ https://issues.apache.org/jira/browse/PIG-3015?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13501340#comment-13501340

Joseph Adler commented on PIG-3015:
-----------------------------------

I just took at look at PIG-2614. It looks like the PIG-2614 patch will be compatible with
this patch; PIG-2614 simply counts errors as values are read from a LoadFunc. Am I missing
something? I'd be happy to drop the option to ignore bad records; I think that would make
the options for this function cleaner and easier to understand.

> 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.
