Zhihong Yu commented on HBASE-4365: ----------------------------------- The above concern makes sense. We'd better make this change before branching 0.94 > Add a decent heuristic for region size > -------------------------------------- > > Key: HBASE-4365 > URL: https://issues.apache.org/jira/browse/HBASE-4365 > Project: HBase > Issue Type: Improvement > Affects Versions: 0.92.1, 0.94.0 > Reporter: Todd Lipcon > Priority: Critical > Labels: usability > Attachments: 4365-v2.txt, 4365.txt > > > A few of us were brainstorming this morning about what the default region > size should be. There were a few general points made: > - in some ways it's better to be too-large than too-small, since you can > always split a table further, but you can't merge regions currently > - with HFile v2 and multithreaded compactions there are fewer reasons to > avoid very-large regions (10GB+) > - for small tables you may want a small region size just so you can > distribute load better across a cluster > - for big tables, multi-GB is probably best -- This message is automatically generated by JIRA.
