Redis tutorial, April 2010 - by Simon Willison. Server backed sessions (where the browser is given a random cookie value which is then associated with a larger chunk of serialized data on the server) are a very poor fit for relational databases.
They are often created for every visitor, even those who stumble in from Google and then leave, never to return again. They then hang around for weeks taking up valuable database space. They are never queried by anything other than their primary key. Database sessions also force an additional SQL statement to be executed for every page view to read that user's session, even if only to update a "Logged in as X" bar at the top of the page. A fast key-value store like Redis is a much better fit for session data. Blog Archive » Redis: Relations in a NoSQL world. Posted: March 23rd, 2010 | Author: Adam | Filed under: NoSQL, programming, Python, Redis | 8 Comments » In the first article in our series on Redis we talked about how to get started and the basics of the simple data structures that are available in redis.
The simple structures are good for basic operations like storing strings and keeping counters but, using it for anything more complex requires relating one set of data to another. At first glance this is a bit of a problem since redis by design is a flat dictionary with no relations but, with a bit of application code and adherence to some mental programming standards you can build some quite complex applications using redis. We hinted at this style of structure in the first article when we got to talking about sets with our reddit like example of story voting.
