Parralel multi-instance load balancing

Hy! I have root process that inits a list of variables. That list contains about 900 instances. From the items of that list created a embedded subprocesses. One subprosess for one item. If I run all 900 subprocesses in parallel, the system is overload and the application server is crashes. If I run it sequentially it have a long time of execution. The best way is to split all instances to chunk of items. One chunk = 50 item. Chunks will be executed in sequential manner. Items from chunk in parallel manner.

My question: Does camunda have some setting for this. Something like loop cardinality settings, but with evaluating all elements from the list, not first ā€˜nā€™ item

Thanks!
