             Summary: Explicit cast support in Drill execution engine
                 Key: DRILL-316
                 URL: https://issues.apache.org/jira/browse/DRILL-316
             Project: Apache Drill
          Issue Type: Improvement
            Reporter: Jinfeng Ni


Explicit cast support currently is not available. Explicit cast would be useful, since 1) once optiq pass the cast function into logical/physical plan, drill execution engine need to parse the cast function in the expression and do the casting work, 2) implicit cast would internally build an explicit cast function call, to do the casting work.
