You won't go wrong with the CloudKVS Lib - works like a dream - and if you follow the rules - it's very quick. For example, a list with 93 records, 23 fields on a 4G connection takes less than 0.3 seconds to download and update the local database.
You could go for a MySQL setup - but that is a whole different ball game and will involve quite a bit of coding, security setups etc and also how do you communicate with your database i.e. via PHP or one for the Libs available on this forum.
