Oracle Database connector details
Estuary’s OracleDB connector captures change events from Oracle databases in real time using Oracle LogMiner. It continuously streams inserts, updates, and deletes into Flow collections, providing a reliable foundation for downstream analytics and CDC pipelines.
- Streams real-time CDC events from Oracle 11g and above
- Supports both standard and container databases (CDB/PDB) setups
- Enables automatic backfills, incremental SCN-based syncs, and dictionary management
- Compatible with secure SSH tunneling for private or cloud-hosted databases
- Supports Estuary’s Private and BYOC deployments for full control and compliance
💡 Tip: For managed Oracle databases on AWS or Azure, Estuary’s connector automatically configures LogMiner and watermark tracking, reducing setup time and ensuring high-throughput CDC performance.
