Users limit

How many concurrent users does it support? How about Rest requests have some request limit?

There’s no limit on concurrent users. the engine doesn’t do anything while users are working on tasks. Only when users complete tasks in parallel.
You can scale the number of incoming requests by adding more nodes to your cluster

I did a stress test connecting 500 users to the platform and it got stuck. The test rode in a very simple machine with only 2GB of memory. Is the limit not in the system but in the machine capacity in which it is installed?

There are a lot of factors to consider

  • The Database you’re using
  • The number of nodes you have
  • The job executor settings
  • The process itself

All of these would have an impact on how the engine would be able to handle a large number of requests.
