Can I change the heap size for Groovy in Beaker notebook?

Question

When I am launching Beaker notebook, can I change the heap size for Groovy? I'd like to customize this if possible.

Answer 1

Yes. To customize the heap size, launch Beaker like this:

beaker.command --plugin-option Groovy:-Xmx8g

Or you can edit your beaker.pref.json file, and get that configuration every time you run Beaker.
