Service Task with Async Continuation Never Executes

We’ve experienced this issue - can I ask - what are the downsides of setting jobExecutorDeploymentAware? It sounds from earlier discussion by @StephenOTT and @Webcyberrob that the REST deployment option requires some work to be a first class citizen? REST is certainly the more desirable deployment option for us - fits better with current deployment tools and pipelines. We are also planning to deploy Camunda via Docker containers.

My best understanding after reading the thread is that if deployment aware is switched off (which it seems is a requirement when deploying by REST), Camunda engines will need to be restarted to become aware of the new deployments?

Also, how does one go about

I’m struggling to find a description of this in the documentation.
