[jira] [Commented] (HBASE-15816) Provide client with ability to set
priority on Operations
[ https://issues.apache.org/jira/browse/HBASE-15816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16069249#comment-16069249 ]
Andrew Purtell commented on HBASE-15816:
----------------------------------------
This patch makes changes to Public/Stable interfaces. They are method additions so would be binary compatible with older versions but client code that uses them would not be compatible with older releases. HBase compatibility guidelines allow this no problem for master, branch-2, and branch-1. I believe it is also allowed for branch-1.3 and branch-1.2 but would like to hear from [~mantonov] and [~busbey] . See PHOENIX-3983 for latest rationale. It would be much easier for Phoenix to pass priority through in RPCs than reverse engineer the client intention on the server side. They'd need support in releasing versions.

> 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.
