> Currently, CBO is bypassed for update/delete/merge statements.
> To support optimizing these statements through CBO, we need to complete three 
> main tasks: 1) support for sort in Calcite planner, 2) support for SORT in 
> AST converter, and 3) {{RewriteSemanticAnalyzer}} should extend 
> {{CalcitePlanner}} instead of {{SemanticAnalyzer}}.
