1. An introduction to Redis
2. What is it? Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets.
3. What is it? Redis is an open source, advanced key-value store. It is often referred to as a data structure server since keys can contain strings, hashes, lists, sets and sorted sets. What?
4. What is it? Think memcached: string => string
5. What is it? Think memcached: string => string But on steroids: string => string/int/list/hash/set
6. What is it? Think memcached: string => string But on steroids: string => string/int/list/hash/set All the operations you’d expect for those types
7. What is it? Think memcached: string => string But on steroids: string => string/int/list/hash/set All the operations you’d expect for those types Plus other weird stuff: sorted sets, pub-sub
8. In memory (ram), very fast (100’s K ops/sec) Storage
9. In memory (ram), very fast (100’s K ops/sec) RDB (binary dump, default), every X sec/op Storage
10. In memory (ram), very fast (100’s K ops/sec) RDB (binary dump, default), every X sec/op AOF (append log), safe but slow Storage
11. Atomic (one event loop) Behaviour
12. Atomic (one event loop) Supports transactions (think batches) Behaviour
13. Atomic (one event loop) Supports transactions (think batches) Most operations O(1) Behaviour
14. Atomic (one event loop) Supports transactions (think batches) Most operations O(1) Extensible with Lua (custom atomic ops) Behaviour
15. Demo time
