It seems it even supports nearest search for lon/lat points by default... Quite nice since most RDMS don't even support it be default.
Although I'm curious to know what algorithm it uses for nearest search, it doesn't talk about it in the doc.
I don't really understand what redis should not be used for, I guess it's not for complex queries? Conventional RDMS really seem to belong to the hard disk drive age. So the difficulty resides in having well designed data schemes.
I adore redis, I use it for tons of stuff, but I still like to keep my single-point-of-truth for critical data in an ACID, transactional relational database.
I frequently denormalize that data INTO redis so I can answer certain classes of queries quickly. I'm also very happy with redis for caching, rate limiting, inter-process-communication, distributed locking and tons of other fun use-cases.
