How does Scala support high-throughput messaging systems?

Scala integrates with Kafka and Akka Streams for scalable messaging systems.

High-throughput messaging systems in Scala rely on Kafka for durable message storage and Akka Streams for processing. Partitioning enables horizontal scaling. Backpressure ensures consumers are not overwhelmed. Serialization formats like Avro or Protobuf reduce overhead. Exactly-once processing semantics are achieved through transactional producers and idempotent consumers.
