      Description

      DatasetService has been the cause for various issues. Main areas of improvement needed:

      • Performance: It can currently not handle many requests, when many flowlets or service handlers start at the same time, some of them get timeouts for their RPC calls.
      • Stability: More graceful handling of transaction failures, high availability
      • Operability: Improve error handling, return meaningful errors, insights into error rate, perhaps metrics, more meaningful logs
