Hi All,

We enabled on-heap caching for our application, as per documentation. The
only change required is to set OnheapCacheEnabled property of
CacheConfiguration. Once we made this change, and started up our
application, ignite metrics still shows onheap and offheap memory.  

Note: we are using ignite v2.3 

Metrics for local node (to disable set 'metricsLogFrequency' to 0)
    ^-- Node [id=0223cd4a, name=delivery, uptime=00:01:00.174]
    ^-- H/N/C [hosts=1, nodes=1, CPUs=8]
    ^-- CPU [cur=2.63%, avg=13.84%, GC=0.03%]
    ^-- PageMemory [pages=111265]
    ^-- Heap [used=468MB, free=75.98%, comm=1948MB]
    ^-- Non heap [used=139MB, free=-1%, comm=143MB]
    ^-- Public thread pool [active=0, idle=0, qSize=0]
    ^-- System thread pool [active=0, idle=8, qSize=0]
    ^-- Outbound messages queue [size=0]


1) Does ignite still has off-heap memory even if onheapCacheEnabled is true?
2) How to ensure onheapCachedEnabled is honored?
3) Do we need to do any other configuration changes?

Regards,
Naresh
