FAQs

How do I replicate PostgreSQL data to Amazon S3?

Sign up for Weld, connect PostgreSQL as a source and Amazon S3 as a destination. Weld handles the extraction, loading, and lets you transform data using SQL or dbt.

What PostgreSQL data can I replicate to Amazon S3?

You can replicate Tables, Views, and Schemas. The available objects depend on your PostgreSQL account permissions and configuration.

How often does Weld replicate data from PostgreSQL?

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 PostgreSQL data before it lands in Amazon S3?

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

Is the PostgreSQL to Amazon S3 integration secure?

Yes. Weld encrypts all data in transit and at rest, is SOC 2 Type II certified, and supports IP whitelisting. Credentials are stored encrypted and never logged.
