event-processor | Spring Integration WS Sample

is there a shorthand way figuring out parameter type based on the json evaluated by readJSON groovy package. I am using resulting event_processor_parameters in a job such as

build job: "dvmt-event-processor-dev", wait: false, parameters: event_processor_parameters

I have this working but I would like to have more cleaner way.

I referred to the example posted here. I am trying to run Multiple spring cloud stream application together. Here the output of first is given as input to other. Below is what I am trying to do.

According to documentation EventProcessorClient is recommended way to consume eventhub streams:

EventProcessorClient should be used for reading events from all partitions in a production scenario, as it offers a much more robust experience with higher throughput.

EventProcessorClient allows to update consumer's offset only inside message handler i.e. for each message, something like:

I've started to use Axon 4.3.1 (latest version) in my project and having a problem.

Where can I config the kafka retry policies after @eventhandler throw an exception?

OBS: I'm using SubscribingEventProcessor type as event processor (both projects). I'm using separate projects! Command model use mongo and publish events on Kafka. Query model consume events from Kafka (eventbus). In this way, using separate JVMs.

@processinggroup(event-processor) is configured to class with event-handler method. I'd like to have a config to Kafka auto retry after some time in error cases (from query model project).

Can I use some default Axon component? Could I use something like spring-retry or internal kafka configs itself?

I've found something like that (documentation):

https://docs.axoniq.io/reference-guide/configuring-infrastructure-components/event-processing/event-processors#error-handling

"Based on the provided ErrorContext object, you can decide to ignore the error, schedule retries, perform dead-letter-queue delivery or rethrow the exception."

How can I config (for example, schedule retries) on @eventhandler after errors?

Could you help me?

Thanks.

I am playing around with axon server locally. I am running a docker container on my local machine via the command docker run -d --name axonserver -p 8024:8024 -p 8124:8124 axoniq/axonserver.

When I start my spring-boot application, my event handler that is external to an aggregate reruns all previous events so I see this stream of log statements on startup.

The same event handler also publishes a command to an aggregate, which then appends a new event to the aggregate that processes the commands. So my aggregate ends up getting a few events tacked on the end of it each time I reboot the application when I would only want or expected one.
