DM-37854
-
Getting issue details...
STATUS
- trying to look at the performance of the worker tasks (how much time is spent executing queries vs sending result sets to Czar). Tasks reported by Qserv worker db06
- MySQL connections that were active at the same time
- Observation: most tasks are in the "stealth" mode. They have booted off their schedules and they are silently sending data (*VERY* slowly) to Czar. No stats exists in Qserv for those.
- details will be reported at the meeting
