BRPOPLPUSH

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, Valkey 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.
