Description

When migrating the stream processors, we need to make sure that all state changes are reflected by events. We want to extract the state changes in the processors/behaviors into a StateWriter that writes an event and apply the state change. The same logic is called on replay to restore the state.

  • create the basic structure (i.e. StateWriter, EventApplier) that can be used by the processors and for replay
