--------------------------------------
Are you still working on this Li?
I think this is an important featured to get into HBase, especially if we want
to do log archival for backups and PIT restores.

> The current bottleneck to HBase write speed is replicating the WAL appends
> across different datanodes. We can speed up this process by compressing the
> HLog. Current plan involves using a dictionary to compress table name, region
> id, cf name, and possibly other bits of repeated data. Also, HLog format may
> be changed in other ways to produce a smaller HLog.
