AECOR: PURELY FUNCTIONAL EVENT SOURCING IN SCALA
summary
Aecor is a Scala library that implements purely functional event sourcing with behaviors as the core abstraction and is already mature and tested in production at Avatar. It uses Akka Cluster for consensus and single writer, separates journaling and a wire protocol, provides CQRS projections and distributed processing, and relies on the final tagless pattern so behaviors interpret into 4–6 effects (including a plain IO effect plus a special handler effect). It works in practice.
