== Reactive Spring Cloud Stream AWS Kinesis Binder to SSE via WebFlux
|
||||
|
||||
This sample demonstrate a simple bridging of AWS Kinesis stream records to the Server Side Events subscribers.
|
||||
The `@StreamListener` sink side is based on the Spring Cloud Stream Reactive support, streaming incoming messages to the `Flux` argument which, in turn, is used as a source for the `@GetMapping` controller.
|
||||
|
||||
The `CloudStreamKinesisToWebfluxApplicationTests` demonstrates:
|
||||
|
||||
- an `AmazonKinesisAsync` client configured against local Kineselite on the `4568` port;
|
||||
- the `TestSource` binding for producing records into the Kinesis stream;
|
||||
- a `WebTestClient` to perform SSE request against embedded Netty started by the `CloudStreamKinesisToWebfluxApplication` Spring Boot application on the random port and subsequent verification of the data produced by the `Flux` from the `@StreamListener` against Kinesis Binder consumer.
