The autopurge feature purges orchestration data associated with terminal statuses. "Terminal" refers to an orchestration state that no longer results in triggering work items. Terminal statuses include:

The autopurge feature purges orchestration data associated with terminal statuses. "Terminal" refers to orchestrations that have reached a final state with no further scheduling, event processing, or work item generation. Terminal statuses include:
 - `Completed`
 - `Failed`
 - `Canceled`
 - `Terminated`
 
-Autopurge ignores orchestration data associated with non-terminal statuses. "Non-terminal" refers to an orchestration that is running, paused, or waiting for a worker. These statuses include:
