- Usage:
-
BLMOVE source destination 〈 left | right 〉 〈 left | right 〉 timeout
- Complexity:
- O(1)
- Since:
- 6.2.0
BLMOVE is the blocking variant of LMOVE.
When source contains elements, this command behaves exactly like LMOVE.
When used inside a MULTI/EXEC block, this command behaves exactly like LMOVE.
When source is empty, Valkey will block the connection until another client
pushes to it or until timeout (a double value specifying the maximum number of seconds to block) is reached.
A timeout of zero can be used to block indefinitely.
This command comes in place of the now deprecated BRPOPLPUSH. Doing
BLMOVE RIGHT LEFT is equivalent.
See LMOVE for more information.
