How does Scala enable event-driven CQRS pipelines at scale?

Scala implements CQRS pipelines by separating command processing from query models using event streams.

In Scala, CQRS pipelines are built using event sourcing systems like Akka Persistence or Kafka streams. Commands generate domain events, which are stored in an append-only log. These events are consumed asynchronously to build read-optimized projections. This separation allows independent scaling of write and read workloads and supports eventual consistency across distributed systems.
