      Description

      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.
