WebFirst of all, knowing when to perform re-partitioning is non-trivial. Dynamic phase changing behaviors 1 of appli-cations lead to ﬂuctuating resource demands, which may cause poor cache utilization under static partitioning. To re-partition the shared cache, we want to clearly capture program phase transitions on-the-ﬂy. Even without phase WebCaching guidance. Cache for Redis. Caching is a common technique that aims to improve the performance and scalability of a system. It caches data by temporarily copying frequently accessed data to fast storage that's located close to the application. If this fast data storage is located closer to the application than the original source, then ...
