[jira] [Created] (CALCITE-1548) Instantiate function objects once per query

Julian Hyde created CALCITE-1548:
------------------------------------

             Summary: Instantiate function objects once per query
                 Key: CALCITE-1548
                 URL: https://issues.apache.org/jira/browse/CALCITE-1548
             Project: Calcite
          Issue Type: Bug
            Reporter: Julian Hyde
            Assignee: Julian Hyde


If a user-defined function is based on a class and its methods are non-static then it needs to be instantiated; at present the code generator seems to instantiate it once per iteration, but it should be instantiated in a static member, therefore once per query.
