Subject [jira] Updated: (HBASE-1892) [performance] make hbase splits run faster
Date Tue, 22 Dec 2009 01:10:18 GMT

Jean-Daniel Cryans updated HBASE-1892:
--------------------------------------

    Attachment: HBASE-1892.patch

Little experiment trying to even further improve the splitting process. Basically it opens
the region right away and then tells the master. The HLog thing I removed is because the debug
was filling my disk, sorry.

Unfortunately, it's not faster. It takes a second to split, in the mean time the client first
notices that the region (under split) isn't served, then refreshes once and the region server
still didn't update .META., then it waits one second and finally finds the new region.

> hbase-1506 tried and failed making splits faster in 0.20 context.  This issue is about
doing it in 0.21 where we'll have to tools to do.
