Re: GoldenGate and foreign keys

Yes, you can do it with Goldengate and treat each table separately independent. But you would encounter parent-child issues later. The idea is to replicate tables with dependents (parent-child) together in one stream of replication so to avoid this issue. If you are planning to do the replication in phases, probably better idea is to combine dependent tables from both schema1 and schema2 and do it in phases.

Hope this helps.

Thanks,
