> Currently LRU cache eviction policy is based on dictionary access count. For cache to
remove a entry its access count must be 0. In dictionary decoder after conversion of surrogate
key to actual value the access count for dictionary columns in query is not getting decremented
due to which it will never be cleared from memory when LRU cache size is configured.
