Akka -- Build powerful reactive, concurrent, and distributed applications more easily

Akka is a toolkit for building highly concurrent, distributed, and resilient message-driven applications for Java and Scala.

Akka is the implementation of the Actor Model on the JVM.

Simpler Concurrent & Distributed Systems

Actors and Streams let you build systems that scale up, using the resources of a server more efficiently, and out, using multiple servers.

Resilient by Design

Building on the principles of The Reactive Manifesto Akka allows you to write systems that self-heal and stay responsive in the face of failures.

High Performance

Up to 200 million msg/sec on a single machine. Small memory footprint; ~2.5 million actors per GB of heap.

Elastic & Decentralized

Distributed systems without single points of failure. Load balancing and adaptive routing across nodes. Event Sourcing and CQRS with Cluster Sharding. Distributed Data for eventual consistency using CRDTs.

Reactive Streaming Data

Asynchronous non-blocking stream processing with backpressure. Fully async and streaming HTTP server and client provides a great platform for building microservices. Streaming integrations with Alpakka.
