Subject [GitHub] orc pull request: ORC-46. Reserve CompressionKind values for LZ4 a...

Github user omalley commented on the pull request:

    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?
