Content of the redis training.
The Workshop take around an hour and a half. It is intended for people with zero knowledge of Redis.
Prior knowledge:
- Basic RMDBS (yes, SQL)
- Shell fluency
- Docker familiarity for eventual troubleshooting
Tech requeriments:
- Docker
- Some unix? userland utilities
- Basic Ruby (for the exercise-3)
Hopefully, you will end up knowing at the end of the workshop:
- What is redis
- What is redis suited for (compared to RMDBS)
- What is redis not suited for (compared to RMDBS)
- What are the basic redis datatypes and operations
- What is redis-cli
- What is time complexity and how it applies in redis
- What is redis-benchmark
- Why you should never use
KEYS *in production - How to implement a basic cache system with redis
What is redis?:
- In memory data structure store (database)
- Schemaless
- "Weakly typed" ?
- In ANSI C
- Single threaded
- Think of it as the typical structures persisted (strings, arrays and hashes)
- Very fast
- Commands in the form of: COMMAND key_name argument1 [...] i.e: SET hola mundo, sets key hola with value mundo
Content:
- Part 1: Basic types and interaction
- Part 2: Relational vs Key-Value and complexity
- Part 3: Practical case
To do the execises:
make start-containers to start the Redis instance and the MySQL instance
make stop-containers to stop the Redis instance and the MySQL instance
make redis-cli to start a redis-cli
make shell-cli to start a shell in the redis container
