----------------------------------------

             Summary: Replace standard java maps for partition counters to more effective data structures
                 Key: IGNITE-5872
                 URL: https://issues.apache.org/jira/browse/IGNITE-5872
             Project: Ignite
          Issue Type: Improvement
          Components: cache
    Affects Versions: 2.1
            Reporter: Alexey Goncharuk
            Assignee: Alexey Goncharuk
             Fix For: 2.2


Currently we have map of Integer -> Tuple <Long, Long> which is passed for each cache group. This is very inefficient as at causes a lot of boxes and overheads in marshalling.
This particular map can be replaced with a sorted primitive array.
