The document outlines the history and features of Redis, an open-source NoSQL database initiated by Salvatore Sanfilippo in 2009 due to MySQL's performance limitations. It highlights Redis's capabilities such as key-value storage, data structures, and atomic operations, along with a user course offered by Eduonix that covers various aspects of Redis. The course includes lectures on data structures, commands, persistence methods, and practical applications with Node.js.

1. History
 Early 2009 - Salvatore Sanfilippo, an Italian developer,
started the Redis project.
 Working on a real-time web analytics solution and
found that MySQL could not provide the necessary
performance.
 June 2009 - Redis was deployed in production for the
LLOOGG real-time web analytics website
 March 2010 - VMWare hired Sanfilippo to work full-time
on Redis (remains BSD licensed)
 Subsequently, VMWare hired Pieter Noordhuis, a major
Redis contributor, to assist on the project.

2. What is Redis ?
 Open-source data structure server
 NoSQL Database
 Organizes data using the key-value storage method
 Perfect for high-performance jobs
 Good for caching or using as a message broker

3. Features
 Data Structures server
 Support different kind of values
 Free and open source
 Easy to use
 Easy to learn

4. Goodness
 Written in C (C99 standard)
 No dependencies
 Detailed command reference that lists time complexity
in Big-O notation. • Very easy to build / install (it’ll
probably “just work”)

5. Data Structure
 Strings
 Strings-as-integers (used by INCR/DECR)
 List of Strings
 Set of Strings (unique list)
 Sorted Set of Strings (and weights) (ZSET)

6. Command Overview
 Strings: get, set, increment, decrement
 Lists: push, pop, length, range, trim
 Sets: add, remove, move, length, intersect union, diff, random
 Other: save, lastsave can be used to force & verify disk persistence

7. Atomic Operations
 LPUSH / RPUSH: append to head/tail of list
 LPOP / RPOP: return & remove first/last element of list
 RPOPLPUSH: return & remove the last element of source
list and push to the head of the destination list
 GETSET: set a key to a new value and return the old value
 MGET/MSET: get or set multiple keys to multiple values
 SMOVE: move a value from one set to another
 No way to group commands (transactions)
