Hi!
Difficult to say without knowing anything about the data, you say "the
object", I assume you have lots of them ?
How big is a serialized object, how many do you have ?
Each entry in the cache have an overhead of around 200 bytes or so, so
1M entries have an overhead of 200MB, pages are 4KB by default, if your
objects are big and use multiple pages you get some overhead there also.
You say it use 8.5GB memory, how much is java heap and how much is other
memory ?

I have a serialized object that I load into memory to use it as a cache for
retrieving data. I am thinking of using Apache Ignite to scale my
application so that I can distribute the object over multiple nodes.
However, when trying to save the object in a single ignite cache, my program
uses around 8.5GB of memory. Without Apache Ignite (i.e loading it directly
to memory and running computations on the object) my program uses only 1.5GB
of memory. So I am wondering how is it using Ignite increases the memory
usage by 8x as that seems to be very high. And what can I do to reduce the
memory size?
Here is my ignite configuration xml

P.S I am using ignite with spring data.
