----------------------------------------
remember to attribute the code to mahout project by adding a notice to
NOTICE.txt
Scott, does Avro have a java generator or is it c-based, like protobufs and
thrift (Jon -- the reason protoc is a heavy dependency is that it's a c binary,
not a jar).
> Create a SchemaTuple which generates efficient Tuples via code gen

> This work builds on Dmitriy's PrimitiveTuple work. The idea is that, knowing
> the Schema on the frontend, we can code generate Tuples which can be used for
> fun and profit. In rudimentary tests, the memory efficiency is 2-4x better,
> and it's ~15% smaller serialized (heavily heavily depends on the data,
> though). Need to do get/set tests, but assuming that it's on par (or even
> faster) than Tuple, the memory gain is huge.
> Need to clean up the code and add tests.
> Right now, it generates a SchemaTuple for every inputSchema and outputSchema
> given to UDF's. The next step is to make a SchemaBag, where I think the
> serialization savings will be really huge.
