Subject [jira] [Created] (DRILL-3248) Explain CTAS statement support
Date Wed, 03 Jun 2015 01:01:49 GMT
Jinfeng Ni created DRILL-3248:

             Summary: Explain CTAS statement support
                 Key: DRILL-3248
                 URL: https://issues.apache.org/jira/browse/DRILL-3248
             Project: Apache Drill
          Issue Type: New Feature
          Components: Query Planning & Optimization
            Reporter: Jinfeng Ni
            Assignee: Jinfeng Ni

Currently, only SELECT query could be put in EXPLAIN statement, and Drill does not support
EXPLAIN CTAS statement.  

One option would be to EXPLAIN the select_query in CTAS directly. However,   with the partition
by clause added in CTAS,  it's not possible to do so any more, since there is no corresponding
"PARTITION BY" clause in the SELECT query. 

Therefore, it is important to extend EXPLAIN to accept CTAS directly.
