{{< note >}} This command's behavior varies in clustered Redis environments. See the [multi-key operations]({{< relref "/develop/using-commands/multi-key-operations" >}}) page for more information. {{< /note >}}
BZPOPMIN is the blocking variant of the sorted set [ZPOPMIN]({{< relref "/commands/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]({{< relref "/commands/blpop" >}}) with the only difference being the data structure being
popped from.
