| The size of cache entries in bytes becomes greater than the maximum memory size; |
| The size of cache entry calculates as sum of key size and value size. |
| <p> |
| Note: Batch eviction is enabled only if maximum memory limit isn't set. |

| This implementation is very efficient since it does not create any additional |
