In this chapter, we’ve looked at commands that typically should cover at least 95% of your command usage in Redis. We started with each of the different datatypes, and then discussed PUBLISH and SUBSCRIBE, followed by SORT, MULTI/EXEC transactions, and key expiration.
If there’s one thing that you should learn from this chapter, it’s that a wide variety of commands can be used to manipulate Redis structures in numerous ways. Although this chapter presents more than 70 of the most important commands, still more are listed and described at http://redis.io/commands.
If there’s a second thing you should take away from this chapter, it’s that I sometimes don’t offer the perfect answer to every problem. In revisiting a few of our examples from chapters 1 and 2 in the exercises (whose answers you can see in the downloadable source code), I’m giving you an opportunity to try your hand at taking our already pretty-good answers, and making them better overall, or making them suit your problems better.
One large group of commands that we didn’t cover in this chapter was configuration–related commands. In the next chapter, we get into configuring Redis to ensure your data stays healthy, and we give pointers on how to ensure that Redis performs well.
