Andrey Mashenkov updated IGNITE-15443:
--------------------------------------
    Description: 
There are a number of places where Map<Integer, Integer> and Map<Integer, Object> are used.
Let's add an optimized Map with a primitive key (IntMap, IntIntMap) to the ignite-core module.

Let's benchmark next candidates and choose one
* IntMap from Ignite 2 with robinhood hashing.
* FastUtils
* Netty
* OpenHFT

  was:
There are a number of places where Map<Integer, Integer> and Map<Integer, Object> are used.

Let's add an optimized Map with primitive key (IntMap, IntIntMap) to ignite-core module
from apache-commons or from Ignite 2.
And replace all non-optimal usages.
