--------------------------------
Summary: Distinguish logical nodes for CTAS and simple create
table statements
Key: TAJO-1589
URL: https://issues.apache.org/jira/browse/TAJO-1589
Project: Tajo
Issue Type: Improvement
Components: planner/optimizer
Reporter: Jihoon Son
Create table statements can have two forms as follows.
* CTAS: create table t as select ...
* Simple statement: create table t (int4 id, ...
In the logical plan, CTAS node must have a child while simple CreateTable node
must not. However, the same CreateTableNode structure are used for both
statements, thereby making confusing and potential bugs.
