We, the Eventuate committers, are pleased to announce the availability of Eventuate 0.2. Eventuate is a toolkit for building distributed, highly-available and partition-tolerant event-sourced applications. It is written in Scala and built on top of Akka, a toolkit for building highly concurrent, distributed, and resilient message-driven applications on the JVM. Eventuate

• derives current application state from logged events (event sourcing)
• replicates application state by replicating events across multiple locations
• allows updates to replicated state at multiple locations concurrently (multi-master)
• allows individual locations to continue writing even if they are partitioned from other locations
• provides means to detect, track and resolve conflicting updates (automated and interactive)
• enables applications to implement a causal consistency model
• preserves causal ordering of replicated events
• provides implementations of operation-based CRDTs
• supports distribution up to global scale.

A more detailed introduction is given in the following documentation sections:

• Introduction
• Architecture

For getting started with Eventuate, take a look at:

• User guide
• Example application

New features in Eventuate 0.2 include:

• Cassandra storage backend for event logs.
• Snapshot capturing and storage for event-sourced actors and views.
• Custom snapshot serialization.
• Example application can now save and recover from order snapshots.

You can find further details in the release notes. If you have any questions or comments, please let us know.
