    MotherDuck connector details

    The MotherDuck connector from Estuary brings Flow collections into MotherDuck tables with cloud-native efficiency. Data is staged in Amazon S3 or Google Cloud Storage, then seamlessly loaded into MotherDuck for low-latency querying and analytics. By supporting both merge operations and delta updates, the connector makes it easy to power CDC pipelines while optimizing for cost and performance.

    • Materializes Flow collections into MotherDuck tables for real-time insights
    • Uses S3 or GCS as a scalable, temporary staging layer
    • Supports delta updates for CDC-style replication and merges for consistency
    • Flexible sync scheduling to balance freshness with resource usage
    • Secure integration with MotherDuck Service Token authentication

    For more details about the MotherDuck connector, check out the documentation page.
