Original Downstream Change Summary New serverStatus field: A 'pass' is scheduled periodically, and aborts transactions older than 'transactionLifetimeLimitSeconds'. "passes" is incremented after a successful pass. For Triage: If the metric stops incrementing, the thread could be stuck trying to abort a transaction. Description of Linked TicketThis thread is imperative to ensure forward progress of the system. Since we've seen multiple hangs where the thread gets stuck, we should add serverStatus metrics which track the number of of transactions killed by the thread. Additionally, we should consider adding a log line to indicate which session(s) the thread is trying to abort. |
