What is the fastest way to start process instances? I tried multiple instance call activity, multi-instance service task with delegate calling runtimeService.startProcessInstanceByKey, single service task with for loop having runtimeService.startProcessInstanceByKey for every variable. In case of 30 000 processes to start, what is the fastest way?
In my experience, all of the above ways take multiple hours, which is unusable.
Camunda version 7.8.
Thanks in advance,
