The diagram above illustrates the key differences. The advantages of data structures make Redis a good choice for:
Recording the number of clicks and comments for each post (hash)
Sorting the commented user list and deduping the users (zset)
Caching user behavior history and filtering malicious behaviors (zset, hash)
Storing boolean information of extremely large data into small space. For example, login status, membership status. (bitmap)
