Grafana open source edition - Limitation to number of organizations and users

We are using grafana 7.3 version (docker container alpine). At present, we are trying to find out whether there is a maximum limit for the number of organizations and number of users.

We would like to know the following for grafana open source edition and how this can be different for an enterprise edition:

  1. Max number of organizations possible in a single instance of grafana installation.
  2. Max number of users possible in a single instance of grafana installation
  3. Max number of users per organization possible
