Zset is an ordered set of string types

Zadd: add the element member,score to the zset named key for sorting. If the element exists, its order is updated.

127.0.0.1 6379 > zadd myzset 1 one

(integer) 1

127.0.0.1 6379 > zadd myzset 2 two

(integer) 1

127.0.0.1 6379 > zadd myzset 3 two

(integer) 0

127.0.0.1 6379 > zrange myzset 0-1 withscores

1) "one"

2) "1"

3) "two"

4) "3"

Zrem: delete the element member in the zset named key.

127.0.0.1 6379 > zrange myzset 0-1 withscores

1) "one"

2) "1"

3) "two"

4) "3"

127.0.0.1 purl 6379 > zrem myzset two

(integer) 1

127.0.0.1 6379 > zrange myzset 0-1 withscores

1) "one"

2) "1"

Zincrby: if the element member already exists in the zset named key, the score of that element is incremented by increment, otherwise the element is added to the collection, and its score value is increment.

127.0.0.1 6379 > zadd myzset2 1 one

(integer) 1

127.0.0.1 6379 > zrange myzset2 0-1 withscores

1) "two"

2) "2"

3) "one"

4) "3"

Zrank: returns the ranking of the member element in the zset with the name key (sorted by score from smallest to largest), which is the subscript.
