[GitHub] [pinot] Jackie-Jiang commented on issue #7448: Support stateful ScalarFunction

   Great proposal!
   Currently the scalar function class is actually stateful (one instance of class in the `FunctionInvoker`). We do have a test for that (see `InbuiltFunctionEvaluatorTest.testStateSharedBetweenRowsForExecution()`.
   The problem is that we don't have a way to initialize the class. IMO there are 2 approaches:
   1. Add an `init()` method and explicitly invoke it on the caller side
   2. Initialize the class when the scalar function method is called the first time
