Redis zpopmax 命令

ZPOPMAX key [count]

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.


Array reply: list of popped elements and scores.
