Using Groovy to access Redis

Redis is an open source data structure server with an in-memory data set. It is called a data structure server, and not simply a key/value store, because Redis implements data structures allowing keys to contain binary safe strings, hashes, sets and sorted sets, as well as lists. This combination of flexibility and speed makes Redis the ideal tool for many applications.

Redis has incredible performance, due to the in-memory data set, but it is still possible to persist the data either by saving a snapshot of the data set to disk once in a while or appending each command to a log.

Redis also supports trivial-to-setup master/slave replication, with very fast non-blocking synchronization, auto reconnection on network split and so forth.

Redis first started in early 2009 as a key value store developed by Salvatore Sanfilippo in order to improve the performance of his own LLOOGG, an analytics product. Redis grew in popularity after getting support from people and companies...
