   Hi @zihengCat, sorry for the late review. Would you tell me more about the motivation of this PR? Currently, the stale pendingSegments are computed by `created time of most recent running task (or complete task if there is no running task) - P1D`. I thought this is safe because 1) when a task is already finished, it's safe to delete all pendingSegments created by that task and 2) when a task is running, its pendingSegments is never deleted by the coordinator. Is there a use case where a flexible retention period is required?
