ZPOPMAX key [count]
Available since: 5.0.0
Time complexity: O(log(N)*M) with N being the number of elements in the sorted set, and M being the number of elements popped.
ACL categories:
@write
@sortedset
@fast
Removes and returns up to count
members with the highest 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 highest score will
be the first, followed by the elements with lower scores.
@return
@array-reply: list of popped elements and scores.
