Replicating the primary key pool

You can either incorporate the key pool into an existing publication, or share it as a separate publication. In this example, we create a separate publication for the primary key pool.

To replicate the primary key pool (SQL)

Create a publication for the primary key pool data.

CREATE PUBLICATION KeyPoolData (
   TABLE KeyPool SUBSCRIBE BY location
);

Create subscriptions for each remote database to the KeyPoolData publication.
```
CREATE SUBSCRIPTION
TO KeyPoolData( 'user1' )
FOR user1;
CREATE SUBSCRIPTION
TO KeyPoolData( 'user2' )
FOR user2;
...
```
The subscription argument is the location identifier.

In some circumstances it makes sense to add the KeyPool table to an existing publication and use the same argument to subscribe to each publication. Here we keep the location and rep_key values distinct to provide a more general solution.
