the simple test i did implied they would be just wanna confirm

eddy davies · Answer

Is it only when top level flow finishes that those files are lost Trying to work out best time to upload to s3 for performance I think it would be better to upload bigger files rather than lots of small ones

Christopher Boyd · Answer

Files are lost when the pod is deleted

eddy davies · Answer

And a pod is only created for top level flow not subflows

Christopher Boyd · Answer

a subflow is a subprocess in the same pod unless you create a new flow run via something like <https docs prefect io api ref orion api deployments h=create flow prefect orion api deployments create flow run from deployment>
