    [ https://issues.apache.org/jira/browse/HBASE-17932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15971284#comment-15971284

Ted Yu commented on HBASE-17932:

On page 2, the first bullet mentions wl-queue while the second bullet mentions large-queue.
Do they refer to the same queue ?

> The Manageable Call Queue aims to provide a unified way to build:
> 1.	Administor can create queue with specified number handler using shell command 
> 2.	Administor can increase/decrease the handler number for the specified queue using
shell command
> 3.	Administor can assign the same type request load to one queue, for example, administor
can assign all the large object write requests to one queue, while assign all the small object
write requests to another queue.
> the feature allow you to change the ipc queues/handlers at runtime and is a improvements
for running multiple workloads on a single hbase cluster in some cases.
