Ted Yu updated HBASE-4010: -------------------------- Resolution: Fixed Hadoop Flags: [Reviewed] Status: Resolved (was: Patch Available) > HMaster.createTable could be heavily optimized > ---------------------------------------------- > > Key: HBASE-4010 > URL: https://issues.apache.org/jira/browse/HBASE-4010 > Project: HBase > Issue Type: Improvement > Affects Versions: 0.90.3 > Reporter: Jean-Daniel Cryans > Assignee: Ted Yu > Fix For: 0.92.0 > > Attachments: 4010-0.90.txt, 4010-v2.txt, 4010-v3.txt, 4010-v5.txt > > > Looking at the createTable method in HMaster (the one that's private), we > seem to be very inefficient: > - We set the enabled flag for the table for every region (should be done > only once). > - Every time we create a new region we create a new HLog and then close it > (reuse one instead or see if it's really necessary). > - We do one RPC to .META. per region (we should batch put). > This should provide drastic speedups even for those creating tables with just > 50 regions. -- This message is automatically generated by JIRA.
