How likely are prefect IDs (i.e.

fabulous-marmot

) to see name collision? I'm looking at having flows spin up temp tables with flow IDs as table names, do I need to be worried about name collision.

the auto generated flow run names, while fairly unlikely to conflict, are not guaranteed to be unique. Flow run ids (uuids) are guaranteed to be unique though. So to be safe I would use the id or if you want the name to be human readable you could append the id or a timestamp to the flow run name
