Redis is an in-memory "data structure server", in that besides simple key-value (think memcached) storage you can also have sets, lists, sorted sets, hashes and more. See redis.io.
This extension adds geo-specific commands and storage to the list of operations supported.
Interesting! Thank you for your answer. I have previously heard that people use that to do cache server for websites. How does that use case is covered by reddis? Also, what are other common use cases for reddis? Thank you.
What reading have you done of http://redis.io/ ? What search terms have you used on your favourite search engine?
People here are generous with their time, skills, and knowledge, but your initial question and your followup makes it sound like you've not even tried to educate yourself.
Steve, you're probably talking to a bot, designed to collect some karma points, to be used for upvoting/downvoting some important article or comment in the future.
Ahaha lol whut?! Seriously, I'm asking questions because all I see are features but no real use cases that I could say that Reddis is useful. I think you may be a litle too defensive.
