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
