[jira] Commented: (HBASE-61) [hbase] Create an HBase-specific MapFile implementation

["Andrew Purtell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-61?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12666015#action_12666015 ] 

Andrew Purtell commented on HBASE-61:
-------------------------------------

I see this on the agenda for the Hackathon on Jan 30. Maybe some of the goals of HBASE-1024 regarding file level scaling and I/O efficiency can be incorporated here?

> 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.
