ReadJournalProvider

A query plugin must implement a class that implements this trait. It provides the concrete implementations for the Java and Scala APIs.

A read journal plugin must provide implementations for both akka.persistence.query.scaladsl.ReadJournal and akka.persistence.query.javadsl.ReadJournal. The plugin must implement both the scaladsl and the javadsl traits because the akka.stream.scaladsl.Source and akka.stream.javadsl.Source are different types and even though those types can easily be converted to each other it is most convenient for the end user to get access to the Java or Scala Source directly. One of the implementations can delegate to the other.
