Xu Mingmin created BEAM-2018:
--------------------------------

             Summary: refine expression of Calcite method/function
                 Key: BEAM-2018
                 URL: https://issues.apache.org/jira/browse/BEAM-2018
             Project: Beam
          Issue Type: Improvement
          Components: dsl-sql
            Reporter: Xu Mingmin
            Assignee: Xu Mingmin


https://calcite.apache.org/docs/reference.html list the method/functions that are supported in Calcite SQL statements. 

In this task, it defines an interface on how to mapping SQL expressions(with method/functions, and those without like direct-field reference) into a Java expression that can be evaluated against row records. 

--It's supposed to replace the reference implementation {{BeamSQLSpELExecutor}} for better capability.
