-------------------------------------
bq. Removed fix version. Fix version is set when the patch is committed.
Yes. Thanks for Akira for checking this. We should use "Target version" to set
versions that this patch is expected to show up. "Fix version" is used by
committer to indicate branches that the commit actually land in the end.

> gzip supports compression levels 1-9. Compression level 4 seems to give best
> compression per CPU time in some of our tests. Right now ZlibCompressor that
> is used by GzipCodec only supports levels 1,9 and six (default).
> Adding all the compression levels that are supported by native ZlibCompressor
> can provide more options to tweak compression levels.
