Getting processInstanceKey like 'XXXXXXXXXXXXXXXX'

Camunda 8 Topics Discussion & Questions
1

I am trying to perform load test on workflow. I am using this client library to start the instance. Intermittently I am getting processInstanceKey=‘XXXXXXXXXXXXXXXX’ in response. What does it mean ? Request was failed to start instance or something else.

  1. I am using zeebe-spring starter library to start instance
  2. I am using self managed zeebe cluster

Hey @umesh_kushwaha

thanks for trying Zeebe. The keys you have observed are expected. In each key the partition id is encoded, which cause the key to look bigger. But essentially the first key is on a partition one plus encoding of the partition id. This makes it possible to generate unique keys in a Zeebe cluster, without collision between partitions.

Does this help?

For the exact calculation/encoding you can take a look here zeebe/Protocol.java at 684c3de1869db58163b51cd5c8474490b5363559 · camunda-cloud/zeebe · GitHub

Thanks for quick reply. It’s mean when we received ‘xxxxx’ instance key, instance started successfully. How we can decode to long. As most of the process instance key is long.

Hey @umesh not sure what you mean by that. The returned key is a long. What is the issue you facing could you post an example?

Hi Zelldon,

Let me simplify my question. Java zeebe client returned below response when fetched Jobs. In below response you can see some of the jobs have key as XXXXXXXXXXXXXXXX this is not a long value. Thats the reason our Jackson converter failed to convert into Object. I wanted to understand the root cause of this response. Co-relation keys are also different for jobs.

Hey @umesh_kushwaha

thanks for your response that sounds really odd. Could you please describe your setup, what kind of client and versions (broker and client) you’re using? Do you see that only on job activation or also on other requests?

Please find the libraries details in above image. I am using below two commands and both command response intermittently throwing the same response

  1. newActivateJobsCommand
  2. newCreateInstanceCommand

Find the zeebe cluster details below image.

Thanks @umesh_kushwaha for the update. Could you provide us a reproducer project? Currently not able to reproduce it. Or please share a bit more code details.

I am using kafka-connect-zeebe Open source repository. kafka-connect-zeebe/ZeebeSourceTaskFetcher.java at master · camunda-community-hub/kafka-connect-zeebe · GitHub

To create process instance, I am using below code snippet.


        @Autowired
    private ZeebeService zeebeService;

final ProcessInstanceEvent event = zeebeClient.newCreateInstanceCommand()
                .bpmnProcessId(zeebeProcessStarterConfig.getZeebeProcessDefinitionKey())
                .latestVersion()
                .variables(processVariables)
                .send()
                .join();
   log.info(
                "Started instance for processDefinitionKey='{}', bpmnProcessId='{}', version='{}' with processInstanceKey='{}'",
                event.getProcessDefinitionKey(), event.getBpmnProcessId(), event.getVersion(),
                event.getProcessInstanceKey());

Hi @Zelldon, I just had a brief discussion with @falko:

  1. This issue seemed to occur with spring-zeebe as well as kafka-connect-zeebe (so it can’t be in the Spring stack)
  2. The customer also said they saw this issue in the server log of the broker, so it seems not to be client library related

The obfuscation of Zeebe process ids was confirmed to be because of logging infrastructure: New Relic's log management security and privacy | New Relic Documentation
