Redis zpopmin 命令

ZPOPMIN key [count]

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.


Array reply: list of popped elements and scores.
