Redis stores all data in RAM, MongoDB uses disk.

If you are not worried about running out of ram use Redis as it is faster.

Redis is better supported than LevelDB right now, some of the LevelDB functionality isn't implemented so I wouldn't use LevelDB yet.

How much RAM do we need for Redis of nodeBB, say, for instance, a very active forum such as this nodeBB community forum?

Keep in mind memory usage goes up the longer the forum is around, since post data is kept in-memory as well.

This forum's been around for about a year -- we're using 40mb.

For this scale and period, the memory size seems very reasonable. Thanks for this great project @julian

sorry for necroposting, i've done my research, i would prefer mongoDB since it's just on the disk side, and not taking much memory like Redis. Memory issues are hard to deal with and messes up your whole server

Solve this with:
# chmod o-rwx /var/lib/redis # chmod o-rwx /var/lib/mongo
If you are the only user with access to the server it's not a big problem. However, it's better to make it inaccessible by other users just in case a cracker get access with non-root user account.
