Now set
auto_increment_increment to 2
auto_increment_offset to 1
on one server and
auto_increment_increment to 2
auto_increment_offset to 2
on the other
… and it is possible to use a plain autoincrement integer as a PK with SJA DATA SYNC and even insert and update records on both servers between syncs.
I described another trick here
http://webyog.com/articles/Using_SQLyog_En…L_Databases.pdf
but this is simpler if you have acces to both server configurations.
.. but still if you want to delete records you will have to do so on both servers, if data exist on both.
