Base aggregate manager.
Provides an Akka-Streams Source that produces EventEnvelopes.
Provides an Akka-Streams Source that produces EventEnvelopes. TODO: document it with implementation example
Does NOT persist the offset forcing a full stream read each time
Defines how the projection offset should be persisted
Persist Last Processed Event Offset as Projection Event in akka-persistence
Persist Last Processed Event Offset as Projection Event in akka-persistence
This implementation is a quick win for those that simply want to persist the offset without caring about the persistence layer.
However, the drawback is that most (if not all) akka-persistence plugins will save it as binary data which make it difficult to inspect the DB to get to know the last processed event.
Read and save from a database.
A ProjectionActor that saves the offset using a CustomOffsetPersistenceStrategy
A ProjectionActor that saves the offset as a snapshot in Akka Persistence

A ProjectionActor that never saves the offset causing the event stream to be read from start on each app restart
Parent actor for all ProjectionActors
Base aggregate manager. Handles communication between client and aggregate. It is also capable of aggregates creation and removal.
