- Moved contents of `spring-cloud-stream-binder-spi` into `spring-cloud-stream`
- Removed `spring-cloud-stream-binder-local` and used local binder implementation for tests exclusively
- instead of publishing to the default exchange, producers now publish to a topic exchange, to which the main queue is bound
- taps on a stream simply bind a queue to the same exchange with a name including the group for the tapping stream and a
routing key pattern `#`
- this means that multiple instances of the same tap stream will compete but multiple tap streams will get a copy
- for partitioned data, a single topic exchange is used, which each partition queue bound with its name as the routing key
- this means taps on partitioned data see the consolidated messages
Remove unused binder utilities.
Use TopicExchange Always
Use a TopicExchange when binding a pubSub producer for consistency.
Remove Deprecated Binder Method
Add group to BindingProperties
- also fix artifact name in test support pom
- also fix some kafka tests (does not imply that kafka taps work - yet)
