BridgeDB will likely need some rather high-level code for interacting with Redis through Twisted in order to complete [Section 2 of proposal #226](https://gitweb.torproject.org/torspec.git/blob/HEAD:/proposals/226-bridgedb-database-improvements.txt#l143). We'll probably want to start with storing the `(emailAddress,timestamp)` pairs for the `bridgedb.Storage.getEmailTime` and `bridgedb.Storage.getWarnedEmail` inside Redis. Other simple datatypes which can be stored in Redis should eventually get listed here (and eventually in [bridgedb-spec.txt](https://gitweb.torproject.org/torspec.git/blob/HEAD:/bridgedb-spec.txt).
