Subject [jira] [Commented] (HBASE-11724) Add to RWQueueRpcExecutor the ability to split get and scan handlers
Date Wed, 13 Aug 2014 19:38:13 GMT

    [ https://issues.apache.org/jira/browse/HBASE-11724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14095995#comment-14095995
] 

Matteo Bertozzi commented on HBASE-11724:
-----------------------------------------

{quote}read.share = 1.0 scan.share = .5 Does this mean that writes are 0%, gets are 50% and
scans are 50%{quote}
almost, but since 0% writes does not make sense you have at least 1 write queue...

{quote}read.share = .5 .scan.share = .5
Does this mean that writes are 0%, gets are 50% and scans are 50%?
Or, does this mean that writes are 50%, gets are 25% and scans are 25%?
{quote}
The second one.. isn't this clear enough?  "will split the READ CALL QUEUES into small-read
and long-read queues".
You split reads and writes, and then you split the scans. otherwise will result too complicate
to understand

can you wordify what you want to see in the doc? I'm a bit stuck here

> RWQueueRpcExecutor has the devision between reads and writes requests, but we can split
also small-reads and long-reads. This can be useful to force a deprioritization of scans on
the RS.
