TransformWithStateMetadataUtils

trait TransformWithStateMetadataUtils extends Logging

This trait contains utils functions related to TransformWithState metadata. This is used both in Scala and Python side of TransformWithState metadata support when calling init() with DriverStatefulProcessorHandleImpl, and get the state schema and state metadata on driver during physical planning phase.
