Subject [jira] [Commented] (HBASE-7084) Raise default minimum region split size
Date Fri, 02 Nov 2012 14:27:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7084?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13489443#comment-13489443

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

You think 1GB would be a better starting point?  It would save us 4x regions on the runaway
tables.

>             Project: HBase
>          Issue Type: Improvement
>          Components: regionserver
>    Affects Versions: 0.96.0

>            Priority: Trivial

> 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.
