Implementation method: analyzing the backup files of a Redis instance;
Advantages of analyzing Redis backup files with the offline full-key analysis function:
1. Quickly discovering the big keys in the instance;
2. Having a full understanding of the occupancy and distribution of keys in memory;
3. Learning about the total number of expired keys, the proportion of keys with an expiration time set, the number of expired keys, the number of evicted keys, etc. to data support for subsequent business optimization operations;
4. Supports creating new backups, analyzing the latest backup files, and also supports full-key analysis of the existing backups;
