"Unlike traditional caches which deal only with key-value pairs, Redis is popular for its support of high performancedata types, on which you can perform atomic operations such as appending to a string, incrementing the value in a hash, pushing to a list, computing set intersection, union and difference, or getting the member with highest ranking in a sorted set. Other features include support for transactions, pub/sub, Lua scripting, keys with a limited time-to-live, and configuration settings to make Redis behave more like a traditional cache."
