Re: How is memory used for the Ignite server node?

Hi Jason,

Provided capacity planning guide can give you rough estimate to start with
and you will have to test case by case after that. I actually think it's way
more risky if you don't do that.

As for the memory consumed by process, remember that both JVM and CLR are
managing their own memory, so it can actually be consumed by temporary
object that are not GCed yet, for example. It also depends on what kind of
load you create on the cluster (only cache, compute, etc.). Generally I
recommend at least 4GB heap memory in case the data is off-heap. If you
don't experience OOM errors or GC pauses, you're good.
