["Kevin Odell (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-7084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13489436#comment-13489436 ] 

Kevin Odell commented on HBASE-7084:
------------------------------------

+1, I think with .90 being an exception as opposed to a rule these days we should use HFilev2 and set the default to something like 2GB and then have our documentation discuss splitting for smaller workloads.  It is much easier to split then it is to merge.

> Several times I've seen folks mentioning to raise region split sizes from the default 256m to something more suitable (mostly folks say 1 GB, sometimes 2 GB, more than other options), in order to control the # of regions explosion once they begin heavy-hitting the tables.
> Perhaps it makes sense to raise the default itself, since there are ways to bring it down per-table if needed by some use-cases?
> Opening this as a discussion first, since this "too many regions" trouble is quite prevalent among newcomers.
