bzpopmin.3valkey - Man Page

Removes and returns the member with the lowest score from one or more sorted sets. Blocks until a member is available otherwise. Deletes the sorted set if the last element was popped.

Synopsis

BZPOPMIN key [key...] timeout

Description

BZPOPMIN is the blocking variant of the sorted set ZPOPMIN primitive.

It is the blocking version because it blocks the connection when there are no members to pop from any of the given sorted sets. A member with the lowest score is popped from first sorted set that is non-empty, with the given keys being checked in the order that they are given.

The timeout argument is interpreted as a double value specifying the maximum number of seconds to block. A timeout of zero can be used to block indefinitely.

See the BLPOP documentation for the exact semantics, since BZPOPMIN is identical to BLPOP with the only difference being the data structure being popped from.
