Change data capture with NineData
Change data capture, often shortened to CDC, is the practice of identifying database changes and moving those changes to another system with minimal delay.
NineData supports CDC-oriented workflows through real-time data replication tasks. These tasks are commonly used for database migration, disaster recovery, data warehouse synchronization, and data integration across heterogeneous data sources.
When to use this workflow
Use a CDC-based replication workflow for these tasks:
- Keep a target database synchronized while applications continue writing to the source.
- Reduce downtime during database migration.
- Feed downstream analytics or integration systems with fresh data.
- Maintain data consistency between cloud and self-managed environments.
