The Microsoft SQL Server connector captures real-time change data (CDC) from your SQL Server database and streams it into Estuary collections, ensuring continuous synchronization across systems.
- Continuous CDC ingestion: Streams inserts, updates, and deletes directly from SQL Server’s CDC change tables into Flow collections for real-time data pipelines.
- Broad platform support: Works seamlessly across self-hosted, Azure SQL Database, Amazon RDS, and Google Cloud SQL instances.
- Automatic schema and instance handling: Detects new capture instances when DDL changes occur (like added columns) and automatically transitions to updated change tables.
- Granular permissions and automation: Supports automatic capture instance management and change table cleanup when granted
db_ownerprivileges. - Flexible and secure connectivity: Connect via SSH tunneling or IP allowlisting for on-premise and cloud-hosted deployments.
- Customizable configuration: Includes advanced tuning options for backfill chunk size, table skipping, and metadata tagging.
💡 Tip: For optimal reliability, enable Automatic Capture Instance Management to let Flow handle table-level CDC setup and schema evolution automatically, while ensuring the user has the necessary db_owner privileges.
