An introduction to Redis

Redis is an in-memory data store. The entire dataset can be stored in memory making reads and writes much faster than relational databases, which is useful for data that is not going to need persistence. In addition, we can store data without making a schema, which is fine if we are not going to need complex queries. In our case, we simply need a data store that will allow us to store messages, get messages, and expire messages. Redis fits our use case perfectly!
