ZPOPMIN 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.

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.

*Return value

Array reply: list of popped elements and scores.
