Hello, I raised this question earlier as well, we want to explore if I can run the ObjectDB completely in Memory ? (without any writes to Disk, it's okay to loose the data if the node is down ).

Questions about the server license

Hi, I'm currently developing alone  a project I don't know if it becomes a future company with income. I'm using the free licence but already have exceeded the amount of types permitted.
