[jira] [Commented] (HBASE-7501) Introduce MetaEditor method that
both adds and deletes rows in .META. table
[ https://issues.apache.org/jira/browse/HBASE-7501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13546452#comment-13546452 ]
Enis Soztutar commented on HBASE-7501:
--------------------------------------
bq. The Delete and Put would be grouped and then written to .META. table in one transaction.
To clarify, it is not one transaction, but one batch RPC right?

> Project: HBase
> Issue Type: Bug
> Reporter: Ted Yu
>
> In review of HBASE-7365, MetaEditor.deleteRegions() and MetaEditor.addRegionsToMeta() are used in RestoreSnapshotHandler.java.handleTableOperation() to apply changes to .META.
> I made following suggestion:
> Can we introduce new method in MetaEditor which takes List of Mutation's ?
> The Delete and Put would be grouped and then written to .META. table in one transaction.
> Jon responded:
> I like that idea -- then the todo/warning or follow on could refer to that method. When we fix it, it could get used in other multi row meta modifications like splits and table creation/deletion in general.
