I’d advocate decoupling your long polling endpoints entirely from the rest of your web app stack. Personally I like Node.js for this, but Tornado would work just fine too (I’ve experimented successfully with Tornado long polling in the past).[... 171 words]
No. SQLAlchemy can talk to all sorts of different DB-API compliant backends, including MySQL Connector/J (Jython only), MySQL Connector/Python, mysql-python (the MySQLdb module) and OurSQL—plus backends for many other databases. See the full list here:[... 50 words]
