Repair workers prioritize the most unhealthy segments. This has the consequence that when we finally begin to reach the end of the queue, a good portion of the remaining segments are healthy again as their nodes have come back online. This makes it appear that there are more injured segments than there actually are. solution: Any time the checker observes an injured segment it inserts it into the repair queue or updates it if it already exists. Therefore, we can determine which segments are no longer injured if they were not inserted or updated by the last checker iteration. To do this we add a new column to the injured segments table, updated_at, which is set to the current time when a segment is inserted or updated. At the end of the checker iteration, we can delete any items where updated_at < checker start. Change-Id: I76a98487a4a845fab2fbc677638a732a95057a94 |
