Pops an element from a list, pushes it to another list and returns it. Blocks until an element is available otherwise. Deletes the list if the last element was popped.
BRPOPLPUSH source
destination timeout
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.
Please see the pattern description in the RPOPLPUSH
documentation.
