Real size of a stored data in IgniteCache

[Vyacheslav Daradur]

Hello everyone.

How do I know real size of a stored data in the IgniteCache?

For example: I created new cache and put one object, and I want to know
real size of one object in cache.

try (Ignite ignite = Ignition.start("cache-config.xml")) {

    IgniteCache<Long, MyObject> cache = ignite.getOrCreateCache("myCache");

    MyObject obj = new MyObject()

    cache.put(obj.getLongId(), obj);
}

I looked at ClusterMetrics and CacheMetrics, but I'am not sure wich method
is real needed to me.

p.s. I haven't found the answer in search.
