Subject [jira] Commented: (HBASE-61) [hbase] Create an HBase-specific MapFile implementation
Date Thu, 22 Jan 2009 01:15:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-61?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12666024#action_12666024

Jonathan Gray commented on HBASE-61:
------------------------------------

Andrew, I've added it to the schedule.  There's 30 mins on TFile followed by 30 mins of general
scalability, so HBASE-1024 should be a good issue to transition the discussion.

> 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.
