1. What is Conflict Detection and Resolution (CDR) in bidirectional replication? Conflict Detection and Resolution (CDR) is a mechanism in Oracle GoldenGate to handle data conflicts that arise in bidirectional (active-active) replication setups, where the same table is being updated at multiple sites simultaneously. 🧠 Why is CDR needed? In active-active replication, changes can occur […]
