redis - Redis Sorted Set的内存公式是什么？

Question

假设我的 Sorted Set 的平均元素是 X 字节，我需要计算 Redis SortedSet 占用多少内存。

Answer 1

If you know the average size of an element before it's stored in redis, just do this:

• Clear redis of all data: command flushall (dumps all databases)
• Command info, check field used_memory_human (should be zero or close to it)
• Add/store data in redis
• info again, check used_memory_human, size indicates memory used by redis to store objects.

Hope it helps
