CREATE SET

Name

CREATE SET --  Create edb-async-replic replication set

Synopsis

CREATE SET (options);

Description

In the edb-async-replic 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 edb-async-replic 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 "subscriber".

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.

Example

     CREATE SET ( ID = 1, 
               ORIGIN = 1,
               COMMENT = 'Tables for ticketing system' );
