    Release Notes - Apache ServiceComb - Version Java-Chassis-1.0.0-m1

Major improvements:

  • Java Chassis can now use Apollo as configuration center. Users can now change configurations like load balancing policy and those changes will come into effect on the fly. See here for more details.

  • Metrics was re-factored. We now uses events for collecting invocation data instead of Hystrix. This reduces the performance penalty of computing metrics. Metrics can now be fetched via ‘/metrics’ using HTTP. See here for more details.

Other Noticeable Changes:

  • The Java Chassis libraries are now under group “org.apache.servicecomb”.
  • We provide out of the box metrics support now. Prometheus is supported.
  • Configuration center was re-factored and moved out from foundation. Support for Apollo was added.
  • Users can now use Object type for calling services.
  • Users can now use Generics for calling services.
  • Better integration with Spring MVC.
  • Upgraded to zipkin2 internally, Java Chassis can now work with zipkin server v1 and v2.
  • We are in the process of supporting reactive programming. Pojo consumer and provider now supports CompletableFuture.
