Through this chapter, we’ve covered topics that can help keep Redis performing well while keeping your data secure against system failures. The first half of the chapter primarily discussed the use of persistence and replication to prepare for failures and deal with failures. The latter half dealt with keeping your data from being corrupted, using pipelines to improve performance, and diagnosing potential performance problems.
If there are two things you should take from this chapter, they are that the use of replication and append-only files can go a long way toward keeping your data safe, and that using WATCH/MULTI/EXEC can keep your data from being corrupted by multiple clients working on the same data.
Hopefully our discussion of WATCH/MULTI/EXEC introduced in chapter 3 has helped you to better understand how to fully utilize transactions in Redis. In chapter 6, we’ll revisit transactions, but now let’s move on to chapter 5, where you’ll learn more about using Redis to help with system administration tasks.
