In general, we recommend MongoDB if you have a large community. Redis will work just fine, although the memory usage does scale up over time as everything is stored in-memory. Just something to consider.
How do you guys persist data
-
You only have redis as a DB... are you worried about scaling issues and/or server restarts? Are there plans on saving to a disk based store (i.e. MongoDB).

Hey @brizna,
Please take a look at Redis' topics on Persistence to read about how it persists data to disk between server shutdowns/restarts.
