runs only once while deploying multiple flows, consider the following strategy:
1. Use a Control Flow: Modify your deployment logic so that push_to_s3
is conditionally executed. For instance, you could use a control flow mechanism to check if the S3 push has already been completed for the current deployment session.
2. Use Prefect Task Caching: Prefect tasks can leverage caching so that if the task's inputs haven't changed, it can reuse the previous result rather than executing again. This is especially useful if your push_to_s3
step doesn't vary across flows or deployments.
3. Create a Separate Deployment Step: Isolate push_to_s3
from the flow deployment steps and run it as a separate step in your CI/CD pipeline or deployment script. This ensures it's only executed once before deploying the flows.
4. Dependency Management: Set up your flows' tasks in such a way that push_to_s3
is a dependency for the initial task of each flow and all the flows are deployed in a manner where this condition is checked just once.
Without direct experience with Prefect 2.x, I can't give you an exact code snippet, but I can suggest looking into the above strategies and adapting them to your specific deployment process.
If you have a unique configuration or if your flows must execute push_to_s3
in a certain way, consider reaching out on the Prefect community Slack or forums with your specific use case for more tailored advice.
Remember to test any changes in a staging environment prior to production to avoid any disruptions. Would you like more detailed guidance on implementing any of these strategies?
