Coming in Zeebe 0.22: Awaitable workflow outcomes

The upcoming 0.22 release of Zeebe includes a feature many users have been asking for: the ability to start a workflow and retrieve its outcome with a single command. The new gRPC command CreateWorkflowInstanceWithResult is available for testing in the current SNAPSHOT Docker image of Zeebe and the zeebe-node-next version of the Node.js client. This command starts a workflow instance and returns the outcome when the workflow completes. Use-cases A common scenario is to start a workflow in response to a REST request, and send back the outcome from the workflow in the REST response. Previous implementations of this relied on a polling worker to retrieve the outcome, and the use of subscriptions to correlate it with the REST request…

The Job Executor: What Is Going on in My Process Engine?

Sometimes we start a process, and after some initial processing, it does not continue for no apparent reason. Usually, this happens at asynchronous continuations or BPMN timer events, so points in the process where the job executor, the process engine’s component for deferred work, takes over. While the job executor is a well-tested and battle-proven piece of software, it is not a closed system. It integrates with a relational database, an application server and the processes and applications it runs. Problems with job execution typically arise in this interaction of components. In this article, we look at common reasons why job execution can be delayed or stuck, how to diagnose, and how to resolve them.
