SLONIK SET MOVE SEQUENCE(7) | Slony-I 2.2.3 Documentation | SLONIK SET MOVE SEQUENCE(7) |
NAME¶
SET MOVE SEQUENCE - Move a sequence from one Slony-I replication set to anotherSYNOPSIS¶
SET MOVE SEQUENCE (options);
DESCRIPTION¶
Change the set a sequence belongs to. The current set and the new set must originate on the same node and subscribed by the same nodes.Caution
Due to the way subscribing to new sets works make absolutely sure that the
subscription of all nodes to the sets is completely processed before moving
sequences. Moving a sequence too early to a new set causes the subscriber to
try and add the sequence already during the subscription process, which fails
with a duplicate key error and breaks replication.
- ORIGIN = ival
- Origin node for the set. A future version of slonik might figure out this information by itself.
- ID = ival
- Unique ID of the sequence.
- NEW SET = ival
- Unique ID of the set to which the sequence should be moved.
EXAMPLE¶
SET MOVE SEQUENCE ( ORIGIN = 1, ID = 20, NEW SET = 3 );
LOCKING BEHAVIOUR ¶
