When I specify memory request for a task/actor, does scheduler take into account the current free heap memory cluster-wide, or it simply subtracts already submitted requests and makes decision based on the reminder?
If later, is it possible to tell the scheduler to monitor memory in real-time?
Also when specifying memory, does it mean heap-memory or obj-store memory (or combined)? Is it possible to request both (i.e. I know my tasks heap usage and how much it will output to obj store), so scheduler knows what to submit without OOMs?
