The editor in this issue will bring you a solution to the full memory of redis cache, which will be analyzed and described from a professional point of view. I hope you can get something after reading this article.

What if the cache data is full?

First of all, it should be clear that the data used for caching is set to expire. If there is no expiration time, it is not called caching, it is called persistence.

What if the cache is full?

Add memory

This is the simplest and roughest way, but the cost is relatively high

Memory elimination strategy

Redis's memory elimination strategy refers to how to deal with data that requires new writes and requires additional space when Redis runs out of memory for caching.

Maxmemory parameter: set maximum memory usage (configuration)

Maxmemory-policy parameter: the corresponding memory elimination rule (configuration). When there is insufficient memory, the memory elimination rule will be set.

The above is the solution to the full memory of redis cache shared by Xiaobian. If you have similar doubts, it will not hinder your understanding with reference to the above analysis. If you want to know more about it, please follow the industry information.
