There used to be no per-query memory limit in OSS, now it's 10MB.
@affo Any reason not to put it back to no limit, or raise it to something higher?
I didn't realize there were new CLI options to configure those.
I definitely think 10MB for OSS users is too low. but hard to say what the right number is tbh.
Let's set these limits to unlimited by default for OSS.
