SLONIK UNSUBSCRIBE SET

Name

UNSUBSCRIBE SET --  End replication of Slony-I set

Synopsis

UNSUBSCRIBE SET (options);

Description

Stops the subscriber from replicating the set. The tables are opened up for full access by the client application on the former subscriber. The tables are not truncated or otherwise modified. All original triggers, rules and constraints are restored.

ID = ival

ID of the set to unsubscribe

RECEIVER = ival

Node ID of the (former) subscriber

This uses unsubscribeset(integer, integer).

Example

    UNSUBSCRIBE SET (
       ID = 1,
       RECEIVER = 3
    );
        

Locking Behaviour

Exclusive locks on each replicated table will be taken out on the subscriber in order to drop replication triggers from the tables and restore other triggers/rules.

Dangerous/Unintuitive Behaviour

Resubscribing an unsubscribed set requires a complete fresh copy of data from the provider to be transferred since the tables have been subject to possible independent modifications.

Version Information

This command was introduced in Slony-I 1.0
