Spine 1.0.0

Base

This is the first public release of base modules.

Notable API changes:

  • SLF4J logging is replaced by Flogger (#451).
  • Protobuf messages generated with Spine plugins may now be built with validation by calling .vBuild() (#409). The generation of separate ...VBuilder classes was removed.
  • External libraries may now register custom validation options (#408).

Core Java

This is the first public release of Spine core modules.

Most notable changes:

  • ServerEnvironment is now responsible for the configuration of the server-wide routines, such as StorageFactory, TransportFactory and Delivery.
  • System Bounded Context is now configurable — #1115. It was simplified and made less intrusive — #1084.
  • Entities now receive messages via Inbox, which supports message sharding and de-duplication in a multi-node environment — #1096.
  • Trace API was introduced — #1090.
  • Errors during the message dispatching no longer throw exceptions. A series of system events was introduced instead — #1104.
  • ConstraintViolated system event was introduced — #1081.
  • BoundedContext configuration was simplified. Also, BoundedContextBuilder is now the only API to set up the context; all the duplicating API calls were removed from the BoundedContext itself — #1108.
  • It is now possible to @Command upon external events — #1116.
  • @Command methods which accept events, may now ignore them — #1114.
  • BlackBoxBoundedContext API was extended with an ability to assert Query and Subscription behavior by using the corresponding test subjects — #1124, #1126.
  • BlackBoxBoundedContext API is now the only way to test the applications built with Spine. The previous unit-testing framework was removed — #1110.
  • Entity @Column API marked as @Experimental, as we can still see a room for API improvement and further changes — #1134.
  • IntegrationBus behavior on handling new BoundedContexts was fixed — #1120.
  • Previously deprecated API was removed — #1122.

Also, we created a chat on Gitter for answering the questions on the framework use. Please feel free to join and say hi!
