Hi, This is a rough overhead for a cache entry object that holds your serialized data model object placed into a cache.
Why are you sure that this overhead is the reason of higher memory consumption? How do you measure original entry size? In fact the overhead can be caused by a number of SQL indexes in the object or some other reason. I would suggest taking a heap dump and have a look at. The dump should give an answer where the memory goes. — Denis > On Jul 20, 2016, at 10:15 AM, November <[email protected]> wrote: > > Hi > > In https://apacheignite.readme.io/docs/capacity-planning .
