> 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.
