Fixes#564
- Correct an issue where if the `cloud` profile is enabled but no Connectors are available,
no `ConnectionFactory` will be created;
- Introduce a property named `spring.cloud.stream.overrideCloudConnectors` that allows
to suppress the use of Cloud connectors in the application and fall back to Spring Boot
configuration. This is provided so that specific binders can be created with arbitrary
connectivity parameters if needed.
- Add documentation.
Fixes#557
Allow for a `defaultCandidate` flag on a binder configuration that, when FALSE,
ensures that the binder does not interfere with the default configuration process.
Fixes#542
- add option for `autoCommitOnError`
- make `autoCommitOnError` follow the state of `enableDlq` - no need to suppress commits if messages will be sent elsewhere
Fixes#509
- prevent autoconfiguration from reducing the existing partition count and/or replication factor
Split `autoConfigureTopics` in two separate settings, one for `autoCreateTopics`
and one for `autoAddPartitions` (to existing topics)
Renamed `defaultMinPartitionCount` to just `minPartitionCount` on the Kafka binder
Add a flag for controlling topic autoconfiguration by the Kafka binder
Fixes#504
- introduces a new binder setting `autoConfigureTopics` that allows the user to disable the automatic creation of topics by the binder
Additional tests for partitioning
Adding missing documentation for `replicationFactor`
Fixes#495
Currently, `minPartitionCount` is available both as a binder default and as a consumer property.
It would be simpler if it only was a binder setting (seeing as it has effect only as a default).
Fixes#498
- Honour the retry settings from ConsumerProperties;
- Add an additional `enableDlq` option in KafkaConsumerProperties that enables forwarding failed messages to a DLQ topic.
In the context of trying to configure Rabbit, the docs mention that the Rabbit config properties be added under `rabbit`:
```
...
binders:
rabbit1:
type: rabbit
environment:
spring:
rabbit:
host: <host1>
...
```
however, the properties should be configured under `rabbitmq` as reference in the [Spring Boot Appendix A](https://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html)
