             Summary: Use skip scan when row value constructor uses leading row key columns

                 Key: PHOENIX-1211
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1211
             Project: Phoenix
          Issue Type: Bug
            Reporter: James Taylor


We currently only use a skip scan for a row value constructor equality or in list expression
is fully qualified. We can fairly easily use it when only some of the leading pk columns are
used.

For example:
{code}
WHERE (a,b) IN ((1,2),(3,4))
{code}
If the PK is (a,b,c), we can still use a skip scan. We need to pass through the slotSpan array
in this case too, to the SkipScanFilter.
