Examples of org.apache.tajo.engine.planner.LogicalPlanner

org.apache.tajo.engine.planner.LogicalPlanner
This class creates a logical plan from a parse tree ( {@link org.apache.tajo.engine.parser.SQLAnalyzer}) generated by {@link org.apache.tajo.engine.parser.SQLAnalyzer}. Relational operators can be divided into two categories as follows:
General operator: this type operators do not affect the tuple schema. Selection, Sort, and Limit belong to this type.
Projectable operator: this type operators affects the tuple schema. Scan, Groupby, and Join belong to this type.
