5. Redis - Concept  What it is  “NoSQL”  Key-value store  In-memory  What it’s not  Definitely not “relational”  Denormalization is your friend

6. Redis - Uses  Caching session data  Processing data at high speeds  Real-time data feeds

7. Where Do I Get It? www.redis.io

8. Types of Data

9.  Keys  Strings  Hashes  Lists  Sets  Sorted Sets  Queue

10. Types of Data - Keys  Identifier – to find your data  Converted to physical address in memory  Key can be any string of characters you want 123456 document:789456

11. Types of Data  Strings person:12345 Joe  Hashes user:1000 username smith password p4ssw0rd9 age 34  Lists friends:1000 123 897 567 891

12. Types of Data  Sets friends:1000 123 897 567 891  Sorted Sets scores:1000 123/500 567/600 891/700 897/800  Another view scores:1000 123 / 500 567 / 600 891 / 700 897 / 800

13. Types of Data  Queue  Publisher  queue  Subscriber  First-in, first-out (FIFO)

14. Interacting With Redis  Command-line tool redis-cli  Redis Commands http://redis.io/commands  Transactions  Server-side scripting via Lua

15. Programming Clients  ActionScript  C, C#, C++, Obj-C  Clojure  Common Lisp DD  Dart  Erlang  Go  Java  Lua  Node.js  Perl  PHP  Pure Data  Python  Ruby  Scala  Tcl Full list at: www.redis.io/clients

16. Replication  Redis can support Master->Slave replication  Write to one master, keeps one or more slaves up to date Master Slave

17. Where’s the Bad and the Ugly?

18. Persistence  Redis is primarily an in-memory database  It is not really a “persistence” engine  All your data must fit in memory  Can configure persistence, but its not true long-term storage  Persistence is only for crash recovery

20. Live Demo!

21. Installation  Red Hat / RPM-based systems (Red Hat, CentOS, Fedora)  Yum install, exists in most of the basic yum repositories yum install redis  Debian-based systems (Ubuntu)  Aptitude install, exists in most apt repositories apt-get install redis  Zip file download from redis.io

22. Configure And Start  Config file: /etc/redis.conf  Start/stop uses service command:  service redis [ start | stop | restart | status]

23. Installing Yum Repository  Redis.io: Only source code  Get Yum repository from FedoraProject.org – Extra Packages for Enteprise Linux: http://fedoraproject.org/wiki/EPEL rpm -Uvh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel- release-6-8.noarch.rpm yum install redis
