A couple of thoughts:
* So Presto has a writer now? If so, we should extend the WriterVersion
with a new id for it so that we can handle bugs that are specific to that
implementation.
* I assume you'll follow the same compression block structure that we used
with zlib and snappy. (Three bytes of header followed by the untagged
compressed bytes.) I'm very concerned that we don't break compatibility with
the C++ and Java readers.
* That is *really* cool that there is a pure Java LZO, Snappy, and LZ4
implementation that is Apache licensed. Does it have a release that is pushed
to Maven central?
