Redis is an advanced key-value store. It is similar to memcached, but the dataset is not volatile, and values can be strings (exactly like in memcached), but also lists, sets, and ordered sets. All this data types can be manipulated with atomic operations to push/pop elements, add/remove elements, perform server side unions, intersections, and so forth. In order to be very fast but at the same time persistent, the whole dataset is taken in memory and from time to time and/or when a number of changes to the dataset are performed, it is written asynchronously to the disk.
