---------------------------------
Summary: InsertNode and CreateTableNode should play their roles
Key: TAJO-543
URL: https://issues.apache.org/jira/browse/TAJO-543
Project: Tajo
Issue Type: Improvement
Components: planner/optimizer
Reporter: Hyunsik Choi
Assignee: Hyunsik Choi
Fix For: 0.8-incubating
Currently, CreateTableNode and InsertNode are just intermediate
representations. They are rewritten to StoreTableNode. But, StoreTableNode does
not contain some necessary fields, such as output table, target table, target
columns, overwrite flag and create table flag. So far, these fields are kept in
QueryContext.
This implementation causes unnecessary and complex rewrite of
DistributedQueryHookManager. As a result, it is hard to maintain and manage
CREATE/INSERT plans.
The main objective of this issue is to improve LogicalPlanner to use
CreateTableNode and InsertNode throughout the planning phase and eliminate
complex rewrite in DistributedQueryHookManager.
