    > 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.
    
    We're going to start working on a writer soon.
    
    > 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.
    
    Yeah, most likely.
    
    > 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?
