Database replication MySQL associations

I connected a postgreSQL database before and this works fine (although very slow, 1000 objects per 3 minutes) with database replication. Also the associations are set and created as set in the mappings. Now I want to connect to a MySQL database and still use the associations. I found in the forum it is possible to connect to a mySQL database by using the custom setting. Is there any solution to make the association in the mapping work for a mySQL database?

Marick, whats the actual question?

Can't relate to “still use the associations” 

Maybe this will help;
