Subject [jira] [Created] (DRILL-2406) Fix expression interpreter to allow executing expressions at planning time
Date Mon, 09 Mar 2015 20:18:39 GMT
Jason Altekruse created DRILL-2406:
--------------------------------------

             Summary: Fix expression interpreter to allow executing expressions at planning
time
                 Key: DRILL-2406
                 URL: https://issues.apache.org/jira/browse/DRILL-2406
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Jason Altekruse
            Assignee: Jason Altekruse
            Priority: Critical
             Fix For: 0.8.0


The expression interpreter currently available in Drill cannot be used at planning time, as
it does not have a means to connect to the direct memory allocator stored at the DrillbitContext
level. To implement new rules based on evaluating expressions on constants, or small datasets,
such as partition information this limitation must be addressed.
