             Summary: LRUMap isn't, and it's too large and complex, needs refactoring.
                 Key: GEODE-8722
                 URL: https://issues.apache.org/jira/browse/GEODE-8722
             Project: Geode
          Issue Type: Improvement
          Components: native client
            Reporter: Matthew Reddington


There exist trivial implementations of LRU caches which can be composed of a pair of standard maps, or a boost bi-map, which would be a more suitable replacement for our existing implementation. What we have makes no distinction between conceptual components - the map relies on the implementation details of its data type, which in turn relies on the implementation details of the map, and both share a dependency on the element expiration mechanism. Business logic is unnecessarily and tightly coupled to the implementation details of the map and has made the thing unmaintainable.

We need a more generic, loosely coupled, maintainable solution, where business logic is separate from the concept of a container.
