SLONIK_UNSUBSCRIBE_SET7
End replication of slony-i set
Usage
FCUNSUBSCRIBE SET (options);F[0]
Overview
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.
FCID = ival F[0]
|
ID of the set to unsubscribe |
|---|---|
FCRECEIVER = ival F[0]
|
Node ID of the (former) subscriber |
Examples
FCUNSUBSCRIBE SET (
ID = 1,
RECEIVER = 3
);
F[0]
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.
