   @gianm Hi, we are using thetasketch with (1M size) . Interesting to find query time group linearly with intervals using timeseries. I think chunkPeriod may help. And also I guess chunkPeriod child query cache make senses .
   
   we have tried 0.17 forkjoin broker merge, still not good enough.
   Ideally, P1d ->10s, P10d ->15s. But reality is P1d ->10s, P10d ->100s.
   
   But we encounter #4826, Would you like to give some suggestion?
