Alan Gates commented on PIG-794:
--------------------------------

Jeff,

Beyond performance what do you see as the big wins of using Avro?  I'm just thinking here
of moving data between MR jobs in a Pig script and between Map and Reduce phases.  I see lots
of advantages to users using Avro to store their data.

> We would like to use Avro serialization in Pig to pass data between MR jobs instead of
the current BinStorage. Attached is an implementation of AvroBinStorage which performs significantly
better compared to BinStorage on our benchmarks.
