FAQs

How do I sync SFTP data to PostgreSQL?

Sign up for Weld, connect SFTP as a source and PostgreSQL as a destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.

What SFTP data can I sync to PostgreSQL?

You can sync Files, Folders, and Documents. The available objects depend on your SFTP account permissions and configuration.

How often does Weld sync data from SFTP?

Sync frequency depends on your Weld plan. Schedules range from every 5 minutes to daily intervals. Each sync processes only new and changed data.

Can I transform SFTP data before it lands in PostgreSQL?

Yes. Weld supports SQL-based transformations in the platform and integrates with dbt Cloud. You can clean, join, and model your data before analysis.
