stack updated HBASE-61:
-----------------------
Attachment: tfile3.patch
This patch includes HTFile, the wrapper around TFile. Also a
HTFilePerformanceEvaluation that does same as MapFilePerformanceEvaluation.
We're writing about 3x faster with tfile but there is something wrong w/ our
random accesses. I'm looking into it.

> Today, HBase uses the Hadoop MapFile class to store data persistently to
> disk. This is convenient, as it's already done (and maintained by other
> people :). However, it's beginning to look like there might be possible
> performance benefits to be had from doing an HBase-specific implementation of
> MapFile that incorporated some precise features.
> This issue should serve as a place to track discussion about what features
> might be included in such an implementation.
