Redis is fast. It’s fast because the data is all in memory. Persistence options are limited. Because of this, many people say, “Redis is for transient data only!” However, sometimes the need for speed and ease of operations can outweigh the durability downsides! In this talk, we look at a real SaaS business using Redis as its (only) datastore. You’ll learn why we decided to go all-in on Redis and the challenges we faced.
