When your Redis cache runs out of room, one setting decides what gets thrown out to make space. Most people never touch it, and the default that ships with open-source Redis is the wrong one for a cache. 😅
The good news: for almost every site, the right answer is simple.
allkeys-lfu keeps the data your visitors hit most often and drops what's gone quiet. That's exactly what you want for a WordPress site, a busy store, or any cache with a clear set of popular pages.
On ScalaHosting you don't open a config file to set it. The Redis Cache Manager in SPanel puts the policy in a dropdown, picks a sensible default for you, and gives every account its own private cache so other people's traffic doesn't affect you. 🚀

Learn what each Redis eviction policy does, when to use LRU, LFU, volatile, allkeys, or noeviction, and how SPanel lets you change the policy without editing config files.
