v-0.2

Closed tickets

All tickets closed in this release are listed here.

New features

• 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.

Enhancements

• Replication fault-tolerance enhancements.
• Replication now working with NAT (using Akka 2.4-M1).
• Many stability enhancements and refactorings.

Breaking changes

• Configuration key changes

  • log.write-batch-size-max renamed to eventuate.log.batching.batch-size-limit.
  • log.replication.transfer-batch-size-max renamed to eventuate.log.replication.batch-size-max.
  • log.replication.transfer-retry-interval renamed to eventuate.log.replication.retry-interval.
  • log.replication.connect-retry-interval removed.
  • log.leveldb.* renamed to eventuate.log.leveldb.*.

• Akka Remoting must now be fully configured by applications.

  akka.actor.provider = "akka.remote.RemoteActorRefProvider"
  akka.remote.enabled-transports = ["akka.remote.netty.tcp"]
  
  akka.remote.netty.tcp.hostname = ...
  akka.remote.netty.tcp.port = ...
  

  Before, Eventuate's reference.conf predefined akka.actor.provider and akka.remote.enabled-transports which is no longer the case. Akka Remoting settings are only necessary if replicated event logs are used.

• Method changes in DurableEvent

  • emitterReplicaId renamed to emitterId.
  • emitterProcessId removed with introduction of emitterId.
  • customRoutingDestinations renamed to customDestinationAggregateIds.
  • defaultRoutingDestination renamed to defaultdestinationAggregateId.
  • routingDestinations renamed to destinationAggregateIds.

• Method changes in EventsourcedActor

  • replicaId to id. Please note that this is a semantic change: replicaId was required to be unique in context of a given aggregateId whereas id must be globally unique.
  • processId removed with introduction of id.

• Method changes in EventsourcedActor and EventsourcedView

  • lastEmitterReplicaId renamed to lastEmitterId.
  • lastEmitterProcessId removed with introduction of lastEmitterId.
  • recovered() renamed to onRecovered().
