CREATE SET - Create Slony-I replication set
CREATE SET (options);
In the Slony-I replication system, replicated tables are organized in
sets. As a general rule of thumb, a set should contain all the tables
of one application, that have relationships. In a well designed
application, this is equal to all the tables in one schema.
The smallest unit one node can subscribe for replication from another
node is a set. A set always has an origin. In classical replication
terms, that would be the ‘master.’ Since in Slony-I a node can be the
‘master’ over one set, while receiving replication data in the ‘slave’
role for another at the same time, this terminology may easily become
misleading and should therefore be replaced with ‘set origin’ and
ID = ival
ID of the set to be created.
ORIGIN = ival
Initial origin node of the set.
COMMENT = 'string'
A descriptive text added to the set entry.
If none is provided, a default value is set; A replication set
so boring no one thought to give it a name.
This uses “schemadocstoreset(integer, text)” [not available as a man
CREATE SET ( ID = 1,
ORIGIN = 1,
COMMENT = 'Tables for ticketing system' );
No application-visible locking should take place.
This command was introduced in Slony-I 1.0
Until version 1.2, it would crash if no comment was provided.
