Pass args on JVM startup

Hi !

I’m hitting the 8G memory limit and wanted to pass the -Xmx startup flag but couldn’t find how to it. I believe it’s useful to be able to customize how the JVM starts up. I’m not familiar with Jupyter’s internals, but is this where the args should be passed ? https://github.com/Kotlin/kotlin-jupyter/blob/3e3ebaa0e47ac885f41552583b12b9110bd40740/distrib/run_kotlin_kernel/run_kernel.py#L42

Or should we pass them somewhere else ?

Cheers !

PS : If you have any tips on how to change the memory limit, I’m still interested 😃

Not sure what config you are looking for (and fully agree we need more doc), but this is what I use to add kernels with different JVM settings:

python -m kotlin_kernel add-kernel --name "XLARGE 16GB" --jvm-arg=-Xmx16G

Could we get some simple example in readme.md that could show where to locate and how to change the configuration file?
Reading this thread I am not sure if setting up some env variables fixes the problem or not.
Not sure if I have to clone the repository and change the config before installing the kernel?
I guess that setting can be found in:
(...)/anaconda3/pkgs/kotlin-jupyter-kernel-0.11.0.61-py_0/share/jupyter/kernels/kotlin/, that’s not obvious to a user when trying out the library and then getting hit with heap size error when loading a testing CSV.
