 # Input sql
 # Parse the sql to SqlNode and validate it.
 # Convert SqlNode to RelNode.
 # Use the RBO & CBO rule to optimize the logical plan.
 # The recommend rule is  run during the optimize logical plan，as MaterializedViewAggregateRecommendRule.
 # The recommend rule parse the logical plan, and recommend the Materialized Views which can rewrite the source SQL.
 # Some recommend materialized views may be merged.
 # Some recommend materialized views may be the same.
 # The recommend materialized views need to sort, and get topN to use. 
 # output recommend materialized views .
