Question

Unrelated issue this morning tried to restart a 4 day old flow run which had some failed tasks it changed some of the task runs from Failed to Pending but they ve been pending all day and aren t running Is there something else I need to do Other team members have recalled this always being the case in the past when they ve tried to use the Restart feature as well thinking face

Quick question are you running on prefect 1 or prefect 2 Edit I just noticed your previous thread referencing the GraphQl API so I m assuming Prefect 1

James Sopkin · Answer

Also it may be the case that when restarting a flow from failed tasks that the tasks will fail or get hung up if they depend on upstream tasks

James Sopkin · Answer

If that is the case it may be worthwhile to use output caching <https docs v1 prefect io core concepts persistence html>

< James Sopkin> It s prefect 1 Might be good to have separate channels for v1 and v2

Ben Ayers-Glassey · Answer

Also regarding caching I should perhaps have mentioned that we re already using `flow result = GCSResult `

Ben Ayers-Glassey · Answer

Maybe this is relevant <https github com PrefectHQ prefect issues 5170> but for now we ve just basically given up on Prefect s restart failed tasks feature and will start to design our flows around the idea of getting as many good inputs through the ETL pipeline as possible instead of crashing the entire flow
