BZMPOP

Usage:
BZMPOP timeout numkeys key [ key ... ] 〈 min | max 〉 [ COUNT count ]
Complexity:
O(K) + O(M*log(N)) where K is the number of provided keys, N being the number of elements in the sorted set, and M being the number of elements popped.
Since:
7.0.0

BZMPOP is the blocking variant of ZMPOP.

When any of the sorted sets contains elements, this command behaves exactly like ZMPOP. When used inside a MULTI/EXEC block, this command behaves exactly like ZMPOP. When all sorted sets are empty, Valkey will block the connection until another client adds members to one of the keys or until the timeout (a double value specifying the maximum number of seconds to block) elapses. A timeout of zero can be used to block indefinitely.

See ZMPOP for more information.
