trait EventAdapter extends WriteEventAdapter, ReadEventAdapter

An EventAdapter is both a WriteEventAdapter and a ReadEventAdapter. Facility to convert from and to specialised data models, as may be required by specialized persistence Journals.

An EventAdapter is both a WriteEventAdapter and a ReadEventAdapter. Facility to convert from and to specialised data models, as may be required by specialized persistence Journals.

Typical use cases include (but are not limited to):

  • adding metadata, a.k.a. "tagging" - by wrapping objects into tagged counterparts

  • manually converting to the Journals storage format, such as JSON, BSON or any specialised binary format

  • adapting incoming events in any way before persisting them by the journal

case class Tagged(payload: Any, tags: Set[String])

The journal may support tagging of events that are used by the EventsByTag query and it may support specifying the tags via an pekko.persistence.journal.EventAdapter that wraps the events in a Tagged with the given tags. The journal may support other ways of doing tagging. Please consult the documentation of the specific journal implementation for more information.
