- Usage:
-
ZPOPMIN key [ count ]
- Complexity:
- O(log(N)*M) with N being the number of elements in the sorted set, and M being the number of elements popped.
- Since:
- 5.0.0
Removes and returns up to count members with the lowest scores in the sorted
set stored at key.
When left unspecified, the default value for count is 1. Specifying a count
value that is higher than the sorted set's cardinality will not produce an
error. When returning multiple elements, the one with the lowest score will
be the first, followed by the elements with greater scores.
Examples
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 "three"
(integer) 1
127.0.0.1:6379> ZPOPMIN myzset
1) "one"
2) "1"
