[jira] [Commented] (HBASE-4374) Up default regions size from 256M to 1G

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

    [ https://issues.apache.org/jira/browse/HBASE-4374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13103397#comment-13103397 ] 

Andrew Purtell commented on HBASE-4374:
---------------------------------------

If we can get online schema edits into 0.92, at least metadata like HTD/HCD attributes, then users can easily change the split points as tables grow. Can add a ruby script helper for this purpose in bin or shell support. Does not take away from talking up presplitting but provides a good alternative if presplitting is not an option for whatever reason (e.g. keyspace distribution not well known).

> HBASE-4365 has some discussion of why we default for a table should tend to fewer bigger regions.  It doesn't look like this issue will be done for 0.92.  For 0.92, lets up default region size from 256M to 1G and talk up pre-split on table creation in manual.
