memcached - redis 如果内存放满了怎么办？

Question

如题，如果内存满是自动删除一些数据还是把冷数据打快照到硬盘，我记得是打快照到硬盘，但听一个人说是满了就自动删了，打快照是只打热数据，是这样的么？

First of all, you need to take a look at the content inside to determine what to do

Answer 2

It depends on your elimination strategy. By default, new data cannot be added when the memory is full
