Participants should be comfortable with basic system administration tasks using linux command line. Some topics require programming or scripting skills. When booking, please list the programming languages that you are familiar with. If there are none, we’ll just issue redis commands from redis-cli.
Overview
Redis is an open source (BSD licensed), in-memory data structure store, used as database, cache and message broker.
Course Outline
Module 1: Initial setup
Redis Releases
Installation
