Hi,

What is the best value for this variables:

max_jobs_to_activate (int): Maximum amount of jobs the worker will activate in one request to the Zeebe gateway. Default: 32

Hi @CMX

“It depends”.

Try it without changing anything, then try it with them set to 1. And see what the performance is.

Exactly what the ideal settings are depends on various factors - amount of time taken in the handler, number of process instances active concurrently, what it means to say “our task handler will process 1 job each time”.

The task handler is called once for each job. So a task handler processes 1 job each time by design. If you mean that you want only one running in parallel (no thread / event loop concurrency of task handler instances), then you need to set the value to 1 to force that “singleton” nature.
