    Reverse ETL

    ELT vs. reverse ETL: Microsoft OneDrive and ClickHouse

    ELT (Extract, Load, Transform) moves data from Microsoft OneDrive into ClickHouse for analysis. This is the approach shown on this page, and the one to use for dashboards, reports, and data models.

    Reverse ETL works the other direction: it pushes enriched data from ClickHouse back into Microsoft OneDrive. For example, you could sync computed lead scores or customer segments from your warehouse into Microsoft OneDrive to personalize outreach.

    Weld supports both directions, so you can build a complete data loop between Microsoft OneDrive and ClickHouse.

    ClickHouse to Microsoft OneDrive
    Incremental syncing
    Weld uses incremental syncing where supported by the Microsoft OneDrive API, loading only new and updated records to minimize data transfer and warehouse costs.
    Schema handling
    Weld automatically manages schema changes. If Microsoft OneDrive adds new fields, they're detected and added to the corresponding ClickHouse tables.
    Data freshness
    Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
    Security
    All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
