HI,

I am using this code to fire a process

 runtimeService
                .startProcessInstanceByKey("hello_world") // have tried execute also

but this is a blocking call, is there a method which is async ?

Hello @sherry-ummen ,

the behaviour of the engine is driven by the process itself.
A good practice is adding the „async before“ flag at the start event.
By doing this, the job executor will run your process from start.

Hope this helps

Thank you

Ohh alright. Is there a way by default I can may all the process start async? Else it would require every person who is creating a process to remember to make it async at the start.

Hello @sherry-ummen ,

usually it is modelled in the process.

An alternative would be to create a process engine plugin containing a deployment listener, I cannot provide an example right now.

Alright. I found one way in Stackoverflow … haven’t tried it https://stackoverflow.com/a/51167300

Do you see an issue with this approach ?

Hello @sherry-ummen ,

this is exactly what I had in mind. In my opinion, this should work.
