Subject [jira] [Commented] (HBASE-15816) Provide client with ability to set priority on Operations
Date Thu, 16 Jun 2016 06:27:05 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15333203#comment-15333203
] 

Andrew Purtell commented on HBASE-15816:
----------------------------------------

[~churromorales] still interested in carrying this forward? I haven't heard much about this
for a while. Is that because the problem to solve has been handled a different way or simply
because I haven't been around much.

I looked at the v1 patch, it's fine, but...

bq.  I'll create another patch for removing the annotation driven priorities

This does make the reading of this patch "interesting", like the double setting of priority
in HTable call implementations. Did you try this and indeed end up with a monster patch? 

When removing annotation driven priorities we'll want unit tests that confirm where we're
expecting QoS != NORMAL_QOS, the patch doesn't change behavior

I think it's fine to submit and review this as a sequence of patches but what should be committed
is a single patch that addresses all relevant issues.

> First round will just be to expose the ability to set priorities for client operations.
 For more background: http://mail-archives.apache.org/mod_mbox/hbase-dev/201604.mbox/%3CCA+RK=_BG_o=q8HMptcP2WauAinmEsL+15f3YEJuz=qbpcya5-g@mail.gmail.com%3E
> Next step would be to remove AnnotationReadingPriorityFunction and have the client send
priorities explicitly.
