Now that I’ve actually used both Redis and MongoDB a little, I have to say I really like them both a lot. In tandem with using these two, I also worked with MemcacheDB and Tokyo Tyrant. I like those too, but I want to write about Redis and MongoDB because they have substantially different features than what I’ve been familiar with in the past.

Redis

For me, the absolute most awesome feature about Redis is the native list data type. I’m already thinking about all the lists I’m going to create:

  • Server logs
  • Software packages
  • States
  • Colors
  • Hardware manufacturers

Yes, I’m really looking forward to having that information readily available!

The fact that lists can be truncated makes circular logging super easy too!

MongoDB

Oooh… I’m not sure where to start on this. I’ve setup a little blog engine on Docunext Labs using MongoDB and I’m impressed! MongoDB is:

  1. Fast
  2. Flexible
  3. Easy to use

It has a nice “vibe” to it. :-)
