I have a Flowable process that gets initiated via an API call. I am making more than 300 API calls at the same time. So now on each request, a process instance is created. But I can see that each of these executes in sequence one by one. I would want all the 300 process instances to be executed in parallel. Is there a configuration in the Flowable engine to set up parallel execution of process instances?

Hey @biyat,

When you say API call, do you mean REST API or Java API? If it is Java API, then it is your responsibility to either use a thread executor when doing the 300 calls, or you start the process instances with start async and let Flowable execute them in parallel.

Cheers,
