Subject [jira] [Commented] (HBASE-11223) Limit the actions number of a call in the batch
Date Wed, 21 May 2014 13:24:39 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11223?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14004651#comment-14004651
] 

Nicolas Liochon commented on HBASE-11223:
-----------------------------------------

This should be managed in the server rather than the client: there are other clients around.
There is already some code in the server around this category of issue (gc due to request
queue, this kind of things).

> Huge batch operation will make regionserver crash for GC.
> The extreme code like this:
> {code}
>     final List<Delete> deletes = new ArrayList<Delete>();
>     final long rows = 4000000;
>     for (long i = 0; i < rows; ++i) {
>       deletes.add(new Delete(Bytes.toBytes(i)));
>     }
>     table.delete(deletes);
> {code}
> We should limit the actions number of a call in the batch.
