             Summary: Implement prototype for thread-per-partition approach.
                 Key: IGNITE-4092
                 URL: https://issues.apache.org/jira/browse/IGNITE-4092

          Issue Type: Task
          Components: cache

Rationale:
- Decrease contention on thread-pool blocking queue head/tail;

- Every thread has separate non-blocking queue;
- Blocking back-off strategy if queue is empty.
