These projects look really solid - they are drop-in replacements for Redis and should offer the most closely matched performance without the need to keep everything in RAM:
Has anyone tried?
I would like to know the difference between this two data strorage.
There are limit , which you suggest to use?
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.
Some comparisons :
So am I to understand that MongoDB is good if we have lesser RAM ?
@meetdilip Yes, but page loads will be slower.
@baris What about LevelDB? Which is better for NoddeBB Redis or LevelDB?
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?
@Ken-OKABE 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.
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
