FAQs

How do I replicate Azure Cosmos DB data to PostgreSQL?

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

What Azure Cosmos DB data can I replicate to PostgreSQL?

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

How often does Weld replicate data from Azure Cosmos DB?

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 Azure Cosmos DB 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.

Is the Azure Cosmos DB to PostgreSQL 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.
