I think it's pretty clear what is going on, so next thing would be in T206189 to set some limits. Bryan advises against setting hard limits on executor, so the options are:

  • Not launching new queries if the thread count too high
  • Limit number of simultaneous queries
  • Limit PipelineOp.Annotations.MAX_PARALLEL
