Why sync SFTP to Google BigQuery?
Ready for analysis.

Centralizing your SFTP data in Google BigQuery lets you join it with other data sources for cross-platform analytics and deeper insights.

Build reliable dashboards and reports by querying SFTP data directly in Google BigQuery using SQL or your preferred BI tool.

  • Centralized data warehouse

    Bring SFTP data into Google BigQuery alongside other sources to create a single source of truth for your organization.

  • Automated reporting

    Replace manual exports and spreadsheet-based reporting with automated pipelines from SFTP to Google BigQuery. Connect BI tools like Looker, Metabase, or Power BI.

Data

What data can you sync?
From SFTP to Google BigQuery.

Weld syncs the objects the SFTP connector exposes into Google BigQuery, and you choose which tables and fields to include. The connector's docs list what is available.

    Weld MCP server

    Ask your agent.
    It queries Google BigQuery for you.

    Connect Claude, Cursor, ChatGPT or your own agent to Weld over MCP. It reads the SFTP context, finds the tables it needs and runs the query in Google BigQuery.

    Under the hood

    Technical considerations.
    What to expect.

    Incremental syncing
    Weld uses incremental syncing where supported by the SFTP API, loading only new and updated records to minimize data transfer and warehouse costs.
    Schema handling
    Weld automatically manages schema changes. If SFTP adds new fields, they're detected and added to the corresponding Google BigQuery 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.
