Subject [jira] [Commented] (HIVE-10091) Generate Hbase execution plan for partition filter conditions in HbaseStore api calls
Date Thu, 26 Mar 2015 03:48:54 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10091?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14381307#comment-14381307
] 

Alan Gates commented on HIVE-10091:
-----------------------------------

I've left some comments on review board.

Also a question.  If I read HBaseFilterPlanUtil correctly this can handle non-boolean expressions
on initial keys right now, but not booleans or expressions on keys beyond the first one. 
I think it's fine to get this checked in as is and and functionality as we go.  I just wanted
to make sure I understood correctly.

> RawStore functions that support partition filtering are the following - 
> getPartitionsByExpr
> getPartitionsByFilter (takes filter string as argument, used from hcatalog)
> We need to generate a query execution plan in terms of Hbase scan api calls for a given
filter condition.
> NO PRECOMMIT TESTS
