how to monitor off heap size used

Hi, I have a two node cluster with 8GB offheap memory configured on each node. To monitor my offheap usage I'm checking the dataregionmetrics..offheapusedsize metric from jmx. But I'm finding that this value never shrinks. I've tried to expand the cluster and expire the caches and it always

RE: key value cache - value size limits or concerns

Wayne, You can stick huge items into ignite as a value of a key store. Have seen design patterns whereas a queueish structure was thrown in as a value corresponding to a key, and clients of queue retrieved the queue by the key, then queued data in/out. Not a high speed solution. What is
