How Can I Update a Deployed Connector SDK Connector?

Question

I have deployed my Connector SDK code. How can I update and redeploy my code?

Environment

Connector: Connector SDK

Answer

To update and redeploy your Connector SDK code, do the following:

1. In your development environment, update the relevant connector.py, dependency file (requirements.txt or pyproject.toml), and configuration.json files as needed.
2. Test your changes locally. For more information, see our Test your custom connector documentation.
3. Redeploy your connector to Fivetran. To learn more, see our Deploy your custom connector documentation.
4. If the connection already exists, confirm the overwrite prompt. If you use --yes with fivetran deploy, the CLI automatically answers Yes to that confirmation prompt. --non-interactive uses the default answer for each y/n prompt.

Once the deployment is complete, the new code is used in the next sync. If you are re-deploying a connector when the existing connection is in the middle of a sync, the running sync completes using the old code.
