BRPOPLPUSH is the blocking variant of RPOPLPUSH. When source contains elements, this command behaves exactly like RPOPLPUSH. When used inside a MULTI/EXEC block, this command behaves exactly like RPOPLPUSH. When source is empty, Redis will block the connection until another client pushes to it or until timeout is reached. A timeout of zero can be used to block indefinitely.

See RPOPLPUSH for more information.

Return

Bulk string reply: the element being popped from source and pushed to destination. If timeout is reached, a Null reply is returned.

Pattern: Reliable queue

Please see the pattern description in the RPOPLPUSH documentation.

Pattern: Circular list

Please see the pattern description in the RPOPLPUSH documentation.

History

• Starting with Redis version 6.0.0: timeout is interpreted as a double instead of an integer.
