Folks, I'm seeing more and more requests from users to add an option to specify the off-heap memory limit globally, for all the caches in total. Currently we allow this only on per-cache level, which can be not very usable sometimes.
E.g., imagine that you have 100GB of RAM and two caches with 50GB limit for each of them. At some point one of the caches can consume all 50GB, while the second is almost empty. You can't add anything to the first cache regardless of the fact that you still have lots of memory available. Can we add such parameter? -Val
