redis memory and cpu spikes

Question

We use redis for some data in our app, and it\'s totally great. I noticed however occasional cpu and memory spikes on the redis-server process.

Answer 1

The docs says: "the Redis AOF works incrementally updating an existing state, like MySQL or MongoDB does, while the RDB snapshotting creates everything from scratch again and again, that is conceptually more robust."
