@ref:[EventSourcedBehavior](persistence.md)s along with @ref:[Persistence Query](../persistence-query.md)'s `EventsByTag` query can be used to implement
Command Query Responsibility Segregation (CQRS).
The [CQRS with Akka 2.6 video](https://akka.io/blog/news/2020/02/05/akka-cqrs-video) is a good starting point for
learning how to use `eventsByTag` to implement CQRS with Akka. Also, watch the introduction to
[Event Sourcing with Akka 2.6 video](https://akka.io/blog/news/2020/01/07/akka-event-sourcing-video).
The @java[@extref[CQRS example project](samples:akka-samples-cqrs-java)]@scala[@extref[CQRS example project](samples:akka-samples-cqrs-scala)]
shows how to do this, including scaling read side processors for building projections.
