object Journal

A com.github.dnvriend.stream.persistence.Journal component is responsible for writing optionally tagged messages into the akka-persistence-journal.

Each message should be tagged by the com.github.dnvriend.stream.persistence.Journal component or using an akka.persistence.journal.EventAdapter before any of the messages can be queried by akka.persistence.query.scaladsl.EventsByTagQuery or akka.persistence.query.scaladsl.CurrentEventsByTagQuery.

Because the component is not an entity, it's name/persistence id is not relevant. To be compliant with akka-persistence, each message will be stored in context of a random ID prefixed with JournalWriter-.
