            QUESTION

            Does Kafka Stream with same sink & source topics with join is supported?
            Asked 2020-Apr-22 at 21:54

            I've a complex Kafka Stream application with 2 flows fully stateful in the same stream :

            • it use a Execution topic as source, enhanced the message and republished back to the same Execution topic.
            • it join another topic WorkerTaskResult, add the result to Execution and published back to Execution Topic.

            The main goal is to provide a workflow system.

            The detailled logic are :

            • an Execution is a list of TaskRun
            • the Execution look at all the current state of all TaskRun and find the next one to execute
            • If any is found, Execution alter their TaskRunsList and add the next one and publish back to Kafka, also it send to another queue the task to be done (WorkerTask)
            • the WorkerTask is proceed outside of the Kafka stream and publish back to another queue (WorkerTaskResult) with a simple Kafka Consumer & Producer
            • the WorkerTaskResult alter current TaskRun in the current Execution and changed the status (mostly RUNNING / SUCCEED / FAILED) and also published back to Execution queue (with Kafka Stream)

            As you can see, the Execution (with TaskRun list) is the state are current application.

            The stream works well when all the message are sequential (no concurrency, I can only have one alter of TaskRun list at the same time). When the workflow became Parallel (concurrent WorkerTaskResult can be join), it seems that my Execution state is override and produce a kind of roolback.

            Example log output:

            ...

            ANSWER

            Answered 2020-Apr-22 at 21:54

            is this pattern (that is not a dag flow as we sink on the same topic) are supported by KafkaStreams ?

            In general yes. You just need to make sure that you don't end up with an "infinite loop", i.e., at some point an input record should "terminate" and not produce anything to the output topic any longer. For your case, and Execution should eventually not create new Tasks any longer (via the feedback loop).

            what is the good way to design this stream to be concurrency safe

            It always depends on the concrete application... For your case, if I understand the design of your application correctly, you basically have two input topics (Execution and WorkerTaskResult) and two output topics (Execution and WorkerTask). When processing the input topics, messages from each input may modify shared state (i.e., a task's state).

            Additionally, there is an "outside application" that reads from the WorkerTask topic and write to the WorkerTaskResult topic? Hence, there is actually a second loop in you overall data flow? I assume that there are other upstream applications that will actually push new data into the Execution topic, too?
