[jira] [Created] (CALCITE-6571) Impossible to create/extend RelOptRule without using deprecated APIs

Stamatis Zampetakis created CALCITE-6571:
--------------------------------------------

             Summary: Impossible to create/extend RelOptRule without using deprecated APIs
                 Key: CALCITE-6571
                 URL: https://issues.apache.org/jira/browse/CALCITE-6571
             Project: Calcite
          Issue Type: Bug
    Affects Versions: 1.37.0
            Reporter: Stamatis Zampetakis


The {{RelOptRule}} class is not deprecated but all the static factories that create operands were deprecated as part of CALCITE-3923.

The deprecation link instructs the user to use {{RelRule.OperandBuilder}} but the latter is an interface and its concrete implementations is private and inaccessible outside the {{RelRule}} class.

In a nutshell, any rule that extends directly from {{RelOptRule}} is forced to use deprecated APIs.
