>
> Records deleted from CachingKeyValueStore appear in range and all queries.
> The deleted record is replaced with an LRUCacheEntry(null), so that when a
> flush happens the deletion can be sent downstream and removed from the
> underlying store.
> As this is valid and needed, the iterator used when querying a cached store
> needs to be aware of the entries where LRUCacheEntry.value == null and skip
> over them
