Subject [jira] [Commented] (HBASE-4296) Deprecate HTable[Interface].getRowOrBefore(...)
Date Thu, 22 Sep 2011 23:55:28 GMT

    [ https://issues.apache.org/jira/browse/HBASE-4296?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113037#comment-13113037

Jonathan Gray commented on HBASE-4296:
--------------------------------------

We are already using the fat thrift client on our 0.90 branch.  I'm in the process of pushing
this all out into open source so we can then pull it back in to our 0.92 based branch.  I'm
happy to put this stuff into 0.92 in Apache as well but it's somewhat featurish :)

Was the method removed in 0.94 already?  Can we just hold off on removing it into 2600 happens
and that way it won't matter and we can commit it anywhere.  Following 2600 we can modify
how it works and just use a normal scanner then?

> HTable's getRowOrBefore(...) internally calls into Store.getRowKeyAtOrBefore. That method
was created to allow our scanning of .META. (see HBASE-2600).
> Store.getRowKeyAtOrBefore(...) lists a bunch of requirements for this to be performant
that a user of HTable will not be aware of.
> I propose deprecating this in the public interface in 0.92 and removing it from the public
interface in 0.94. If we don't get to HBASE-2600 in 0.94 it will still remain as internal
interface for scanning meta.
