Doug Cutting commented on PIG-794:
----------------------------------
> I think we have to ask the Avro team to support this (current position in the
> stream) for us to proceed with this.
ValueReader performs no buffering, so its position is always the same as the
InputStream that it wraps. See DataFileReader#SeekableBufferedInput for an
example of an input stream that tracks its position.
Note that AVRO-25 proposes to add buffering to ValueWriter, so that the
position of the underlying stream might be different than that of the
ValueWriter, but I do not forsee a need to add this to ValueReader, the concern
here.

> 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.
