Description

Every time Autosaving cache stores to disk, it calls KeyCacheSerializer for every key. In the serialize method, we use this
RowIndexEntry entry = CacheService.instance.keyCache.get(key);
Instead it should use getInternal to avoid updating the stats.
RowIndexEntry entry = CacheService.instance.keyCache.getInternal(key);
