region
[ https://issues.apache.org/jira/browse/HBASE-9081?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Jieshan Bean updated HBASE-9081:
--------------------------------
Summary: Online split for an reserved empty region (was: Online split for an reserved empty region with splits >= 1)
> Online split for an reserved empty region
> -----------------------------------------
>
> Key: HBASE-9081
> URL: https://issues.apache.org/jira/browse/HBASE-9081
> Project: HBase
> Issue Type: New Feature
> Components: master, regionserver
> Reporter: Jieshan Bean
>
> We already have a region splitter tool. But it can only provide limited functions:
> 1. Create table with a specified region number without give any splits.
> 2. Roll-Split on an exist region.
> We have such user scenario:
> Table was created with splits like below:
> a____b____c____d____e____f____g____o
> g~o is a reserved empty region. Will use it only after some days. So we don't know the rowkey distribution currently. Will split it only when it get used.
> Say, we want to split g~o with 10 new regions, likes g, g1, g2, g3, g4, g5.......,g9, o.
> I didn't find similar function has already been there. Please tell me if I am wrong.
> Hope to hear your ideas on this:)
