What's the small amount of memory that a local Pinot can use? I started up a local broker, server and controller and zookeeper and it seems like it needs a 1g of memory. How can I reduce the size of this?

i think you can change jvm setting for this

What should I expect though? I started errors if I set xmx too low.

hmmm, but you want to cap on the memory right ? However it’s true that if xmx is low then pinot cannot start
