PlayNice.ly: Using Redis to store all our data, hahaha (Redis London Meetup)

#redisldn Welcome (The First) London Redis Meetup @robbiehudson @adamcharnock @bash

#redisldn The Agenda • Quick Redis introduction • Using Redis to store all our data, hahaha (Rob & Adam / PlayNice.ly) • Queuing and non-persistent lists (Thomas / Mint Digital) • Super-fast caching and Redis (Demis / mFlow) • QA

#redisldn Onwards!

#redisldn What is Redis?

#redisldn What is Redis? • Advanced key value store • Data Structure Server (+ more!) • Lists, Sets, Hashes (and lots of other cool stuff) • Super-fast in Memory • But it is persistent, and now supports VM

#redisldn Created by... Salvatore Sanﬁlippo (@antirez) ... now VMWare ... and Pieter Noordhuis

#redisldn Redis and PlayNice.ly • PlayNice.ly: Collaboration web app for software developers... • So, a bug tracker :) • And we store all our information in Redis • users, projects, bugs, comments, audit logging, search indexes...

#redisldn Redis schema example • Why you need a schema? ho ho ho

#redisldn Users user:5:name → “Pete Mascot” user:5:username → “pete” user:5:email → “pete@playnice.ly”

#redisldn Projects project:9:name → “Alan Parson’s Project” project:9:created_at → 1274815155 ...

#redisldn Linking users to projects user:5:projects → SET(2, 9, 13) project:9:users → SET(3, 5, 9)

#redisldn But that looks like hard work! • Yes it is, so use a model!

#redisldn ORM for Redis • Ohm: http://ohm.keyvalue.org (Ruby) • http://github.com/nateware/redis-objects (Ruby) • http://github.com/whoahbot/dm-redis-adapter (Ruby) • http://github.com/kijin/stalkr (PHP, “not production ready”) • Roll your own (like we did, for Python)

#redisldn A quick example >>> user = models.User.create() >>> user.user_id 6 >>> user.name = "Pete" >>> user.name u'Pete' >>> user.projects []

#redisldn A quick example >>> project = models.Project.create() >>> project.project_id 8 >>> project.users []

#redisldn A quick example >>> project.users.add(6) >>> project.users [6] >>> user.projects [8]

#redisldn Proving it actually worked... >>> redis.get("user:6:name") 'Pete' >>> redis.smembers("project:8:users") set(['6']) >>> redis.smembers("user:6:projects") set(['8'])

#redisldn Summary • It is very fast! • Other cool stuff: • search • migrations • message queuing • PlayNice.ly is entering into Private Beta in the next few weeks!
