             Summary: Prune all partitions if an always-false runtime filter is 
                 Key: IMPALA-5789
                 URL: https://issues.apache.org/jira/browse/IMPALA-5789
             Project: IMPALA
          Issue Type: Improvement
          Components: Backend
            Reporter: Tim Armstrong

The scenario is as follows:
* A query joins a large partitioned table with another table on a non-partition 
* All of the rows on the build side are filtered out, so the join has an empty 

Currently what happens is that all partitions of the large table are scanned 
and the runtime filter filters all the rows out after materialization.

What would ideally happen is that the scan would notice that the runtime filter 
always returns false and prune all of the partitions.
