This article is about how redis sets the maximum memory footprint. The editor thought it was very practical, so I shared it with you as a reference. Let's follow the editor and have a look.

Setting method:

The Redis setting takes up the maximum memory of the physical machine.

# maximum 20Gmaxmemory 20480mb

Redis settings memory can not be installed, limited deletion is about to expire.

Active cleanup policy is triggered when the current used memory exceeds the maxmemory limit

Volatile-lru: LRU only key with expiration time set (default)

Allkeys-lru: delete the lru algorithm's

Keyvolatile-random: random deletion is about to expire

Keyallkeys-random: random deletion

Volatile-ttl: delete the expiring

Noeviction: never expires, returns an error when mem_used memory has exceeded the maxmemory setting, for all read and write requests

# Delete the maxmemory-policy volatile-ttl that is about to expire after the expiration. Thank you for reading! The method of setting the maximum memory consumption of redis is shared here. I hope the above content can be of some help to you, so that you can learn more knowledge. If you think the article is good, you can share it and let more people see it.
