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
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.
SLONIK EVENT CONFIRMATION BEHAVIOUR ¶
Slonik waits for the command submitted to the previous event node to be
confirmed on the specified event node before submitting this command.
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.
This command was introduced in Slony-I 1.0
