      Description

      This ticket is a placeholder to figure out between ourselves and with TSE what supportability and diagnosability enhancements we might need to include for retryable writes.

      Things that come to mind include:

      • FTDC metrics for number of active sessions
      • Metrics for the CPU (and if possible I/O) overhead of maintaining the retryability metadata
      • Metrics for number of writes which have been retried
      • If we end up with a cache, metrics for hit-rate
