FAQs

How do I replicate Heroku PostgreSQL data to Snowflake?

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

What Heroku PostgreSQL data can I replicate to Snowflake?

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

How often does Weld replicate data from Heroku 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 Heroku PostgreSQL data before it lands in Snowflake?

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 Heroku PostgreSQL to Snowflake 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.
