  3. final case class MergeableOffset[Offset](entries: Map[String, Offset]) extends Product with Serializable

    The core abstraction in Akka Projections.

    A projection instance may share the same name and Envelope, but must have a unique key. The key is used to achieve processing parallelism for a projection.

    For example, many projections may share the same name "user-events-projection", but can process events for different sharded entities within Akka Cluster, where key could be the Akka Cluster shardId.

    Envelope

    The envelope type of the projection.

  6. trait ProjectionContext extends AnyRef

  7. final class ProjectionId extends AnyRef
  8. sealed trait RetryRecoveryStrategy extends HandlerRecoveryStrategy
  9. abstract class StatusObserver[-Envelope] extends AnyRef

    Track status of a projection by implementing a StatusObserver and install it using Projection.withStatusObserver.

  10. sealed trait StrictRecoveryStrategy extends HandlerRecoveryStrategy
