Dear hakkers,

We’re happy to release another milestone of Akka Projections, version 0.2. The API is still under development and might change for upcoming milestones. Feedback, bug reports and feature requests are welcome as issues in akka-projection/issues.

Highlights of the release:

  • insight to Projection status with StatusObserver API
  • offset management API
  • possibility for processing with Akka Streams Flow
  • avoid processing of in-flight messages from revoked Kafka partitions
  • option to group envelopes before the handler
  • make atLeastOnce parameters optional and configurable
  • withRestartBackoff settings directly on Projection
  • define HandlerRecoveryStrategy at the Projection level instead of in the handler
  • configurable table names and improved Cassandra configuration
  • ActorSystem instead of ClassicActorSystemProvider

The documentation can be found at https://doc.akka.io/docs/akka-projection/current/.

A total of 19 issues were closed in this release. The complete list can be found on the 0.2 milestone on github.
