Dmitriy V. Ryaboy commented on TAJO-30:
---------------------------------------

Hi folks,
Just popping in to confirm that you do *not* need to take on a thrift dependency to use Parquet.

Although internally the parquet format is described as thrift, the dependency is not forced
on consumers; it's an implementation details that does not leak out of the Parquet APIs. Furthermore,
we "shade" all the thrift classes, so even if you do take a thrift dependency later on, and
if it's a conflicting version of thrift (some API-incompatible change or something like that),
things will just keep on working.

I think so far, we've managed to not have any non-parquet dependencies at all for the core
packages (when we do pull things in, we shade them; and we are very picky about what we do
pull in).

> Parquet is very promising file format developed by twitter. We need to investigate the
applicability of Parquet. If possible, we implement Parquet port.
