3.7 Other commands

So far we’ve gone through the five structures that Redis provides, as well as shown a bit of pub/sub. The commands in this section are commands that operate on multiple types of data. We’ll first cover SORT, which can involve STRINGs, SETs or LISTs, and HASHes all at the same time. We’ll then cover basic transactions with MULTI and EXEC, which can allow you to execute multiple commands together as though they were just one command. Finally, we’ll cover the variety of automatic expiration commands for automatically deleting unnecessary data.

After reading this section, you should have a better idea of how to combine and manipulate multiple data types at the same time.
