> There is no way to use compression with the C++ DataFileReader and C++ DataFileWriter,
from what I can tell. Adding compression of the written blocks using boost streams is relatively
straight forward and I can provide a patch if people are interested. 
> However, there are a couple caveats:
> - the windows builds of boost don't currently include zlib support (required for compression)
by default. You have to do extra work to get it.
> - I don't know if doing it that way is compatible with other avro implementations
