SET MOVE SEQUENCE

Name

SET MOVE SEQUENCE --  Move a sequence from one edb-async-replic replication set to another

Synopsis

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
);
