The SQL Server Change Tracking connector continuously captures updates from Microsoft SQL Server tables into Estuary collections using native Change Tracking. It delivers real-time replication with lower source database overhead by tracking primary key changes rather than full row logs. This option is ideal when all tables have primary keys and when computed columns need to be captured, which traditional CDC cannot support.
- Uses SQL Server Change Tracking for real-time change capture
- Lower storage overhead compared to log-based CDC
- Supports computed columns and computed primary keys
- Requires primary keys and CT enabled at database and table levels
- Configurable retention period to prevent re-sync gaps
- Works across self-hosted SQL Server, Azure SQL, Amazon RDS, and Google Cloud SQL
