---------------------------------
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.
