I mostly like how there is such a big community around redis. I use redis with ruby on rails, and I just keep coming up with uses for it! All the apis they provide and then are available via the redis-rb gem make accessing redis dead simple.
What do you dislike?
Redis has never disappointed me, so I don't have anything I don't like about it.
Recommendations to others considering the product
Redis is a dream when you use the redis-rb gem.
What business problems are you solving with the product? What benefits have you realized?
I'm using it for helping with background task running, for confirming emails, for inviting collaborators, and soon for aiding in deploying of my ember front-end.
