Subject [jira] [Commented] (HBASE-10126) guarantee atomicity of multi-row mutation within a same region from a single HTable.batch
Date Thu, 12 Dec 2013 03:02:09 GMT

    [ https://issues.apache.org/jira/browse/HBASE-10126?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13846022#comment-13846022

Enis Soztutar commented on HBASE-10126:
---------------------------------------

[~lhofhansl] FYI. 
I am not completely against the idea for enabling single-region atomic updates, however, this
should only be used for a custom region split policy which might make the API confusing for
the users. 
Also, I think we should fix HBASE-9797 first before adding a general API.

> We use this improvement together with DelimitedKeyPrefixRegionSplitPolicy.java to implement
local secondary index without the help of coprocessor.
