Akka Projections 1.0.0-RC1 Released

Dear hakkers,

The Akka contributors are happy to announce the first release candidate of Akka Projections, version 1.0.0-RC1. If no serious bug is reported this RC1 will become GA.

We consider the API stable even though we’re still not making any bincompat promise and you should consider all the public API as ApiMayChange. It might be changed based on feedback from initial usage.

Feedback, bug reports and feature requests are welcome as issues in akka-projection/issues.

Highlights of the release:

  • Unified schemas for JDBC and Slick
  • Support blocking in JdbcHandler start/stop
  • StatusObserver fine grained callbacks
  • Converged StatusObserver semantics to Telemetry: progress reports iff offset has been committed
  • Fix: ClassCastException after restart when using Kafka source
  • Fix: MetadataClientAdapter actor already terminated message when restarting a Projection
  • Fix: JdbcSettings fails when using variable substitution
  • Many documentation improvements

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

A total of 45 issues were closed in this release. The complete list can be found on the 1.0.0-RC1 milestone on github.
