Is there a way to put a hard limit to the memory usage? The community edition for 4.0 has a limit of 6 GB, but I would like to limit the memory usage to 2 GB instead.

No, there isn't a way to limit it downward.

You can call SetMaxWorkingSetSize on Windows if you really want to, and run in a limited namespace on Linux, but these are OS level settings.

Well then how does the license limit it?

We also call to SetMaxWorkingSet. However, there is no way to provide a smaller value.

Alright, thank you!

I suppose I need to build it myself in order to add the option to call SetWorkingSet with a custom value :)

You can actually do that externally via a script :-)

(ps RavenDB).MaxWorkingSet = $maxSize

Great idea, thank you!
