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

             Summary: Refactor segments array in PageMemoryNoStoreImpl
                 Key: IGNITE-4921
                 URL: https://issues.apache.org/jira/browse/IGNITE-4921
             Project: Ignite
          Issue Type: Improvement
    Affects Versions: 2.0
            Reporter: Ivan Rakov
            Assignee: Alexey Goncharuk


In current version of PageMemoryNoStoreImpl, offheap memory is split into equal segments. Quantity of segments is based on MemoryConfiguration#getConcurrencyLevel (or Runtime#availableProcessors, if previous is not set).
This approach is obsolete. In order to reduce code complexity, segments should be refactored into one memory region.
