BUILDING A REAL-TIME AUCTION ENGINE USING EVENT SOURCING
summary
A real-time auction engine built in six months by a four-person team, written in Scala with Akka, uses a custom Atomic Store on Akka Persistence to append events and validate them before publishing via Akka Cluster distributed pub/sub; the system favors CP consistency over availability, generally handles ~10 events/hour (burst up to ~10 events/sec), serializes messages with protobuf, stores metadata in Postgres, and runs successfully on a three-node AWS cluster in production.
