Is the ISA-L zlib support sufficient to read and write the ORC files with
zlib compression? I agree with Gopal that it doesn't feel like a separate
compression codec.
I'm don't think it is a good idea to build in support for proprietary
compression formats. If it is just an optimization on performance, that might
be workable. As a unique codec, it isn't.
