Redis is an open-source advanced key-value cache and data storage, which provides a heightened durability. It is often perceived as a data structure server, as far as keys can contain different types of data: strings, hashes, lists, sets, sorted sets, bitmaps and hyperloglogs. All of these data elements can be processed with different atomic operations, such as appending to a string, pushing an element to a list, incrementing the value in a hash, getting the member with the highest ranking in a sorted set, etc.

One more important Redis feature is an outstanding performance. It is achieved by means of operating with in-memory datasets. In order to store such a database you can use either dumping to disk every once in a while or appending each command to a log. This persistence can be also optionally disabled, if all you need is just a feature-rich, networked, in-memory cache.

And now let’s figure out how to get your own CirrusGrid environment with Redis data structure server in it just within a few clicks.
