[jira] [Created] (IMPALA-10023) Intelligently evict in-memory partitions for higher-cardinality partitioned top-N

Tim Armstrong created IMPALA-10023:
--------------------------------------

             Summary: Intelligently evict in-memory partitions for higher-cardinality partitioned top-N
                 Key: IMPALA-10023
                 URL: https://issues.apache.org/jira/browse/IMPALA-10023
             Project: IMPALA
          Issue Type: Sub-task
            Reporter: Tim Armstrong


The initial patch for IMPALA-9853 will have a placeholder policy for evicting in-memory partitions. We could be smarter and try to return partitions that are filtering input rows effectively.
