Joseph Adler commented on PIG-3015:
-----------------------------------
I think that approach makes sense; each object in a file should be wrapped in a
Tuple. Suppose that a file example.avro contained the data:
{[1, 2, 3, 4, 5]}
{[6, 7, 8, 9, 10]}
and had this schema: {"name" : "IntArray", "type" : "array", "items" : "int"},
and we loaded this as
A = LOAD 'example.avro' USING AvroStorage;
The bag A would have the Pig schema A:{(IntArray:{(int)})}; it would contain
two tuples, which would in turn each contain one bag of integers. Does that
sound correct? If so, I'll go implement that.

> 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.
