Subject [jira] [Commented] (HBASE-4210) Allow coprocessor to interact with batches per region sent from a client(?)
Date Mon, 25 Feb 2013 19:14:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4210?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13586163#comment-13586163
] 

Ted Yu commented on HBASE-4210:
-------------------------------

{code}
+   * @param miniBatchOp batch of Mutations getting applied to region as one batch.
{code}
'as one batch' is redundant.
{code}
+ * @param <T> Pair<Mutation, Integer> pair of Mutations and associated rowlocks
.
{code}
'associated rowlocks' -> 'associated rowlock Ids'
{code}
+  public boolean hadPreBatchMutate() {
+  public boolean hadPostBatchMutate() {
{code}
The above methods can be package-private, right ?

> Currently the coprocessor write hooks - {pre|post}{Put|Delete} - are strictly one row|cell
operations.
> It might be a good idea to allow a coprocessor to deal with batches of puts and deletes
as they arrive from the client.
