问题 I am trying to see if the error channel I am passing to @ServiceActivator can be bounded/parameterized referring the value specified in YAML instead of hardcoding actual destination and consumer group in the code itself. @ServiceActivator( // I do not want to hardcode destination and consumer group here inputChannel = "stream-test-topic.my-consumer-group.errors" ) public void handleError(ErrorMessage errorMessage) { // Getting exception objects Throwable errorMessagePayload = errorMessage

问题 I tried to keep the title as explicit and simple as possible. Basically, I need to intercept the usage of Cloud stream's @Input and @Output annotations. This is needed to automatically add a specific ChannelInterceptor to each MessageChannel.

For example, if I declare this advice @Around("@annotation(org.springframework.cloud.stream.annotation.Input)") public Object

问题 Current setup - I am streaming data from 16 single partitioned topics and doing KTable-KTable joins and sending an output with aggregated data from all streams. I am also materializing each KTable to local state-store. Scenarios - When I tried running two app instances, I was expecting it kafka streams to run on single instance but for some reason it ran on other instance too. Looks like it can created stream task on other app instance during kafka streams failure on instance#1 during to some
