Hello, We're running Flink 1.14 with scala, and we're suspecting that performance is suffering due to serialization of some scala case classes. Specifically we're seeing that our Case Class "cannot be used as a POJO type because not all fields are valid POJO fields, and must be processed as GenericType", and that the case class "does not contain a setter for field X". I'm interpreting these log messages as performance warnings.
A simple case class example we're writing to state that triggers the mentioned 'warnings': case class Progress(position: Int, eventTime: Int, alive: Boolean) I'm understanding the docs that case classes with primitive types should be supported "out of the box". Any tips on how to proceed ? Kind regards, Lars
