   @ly923976094 In Pinot, `segment push` is pretty much the same as `segment upload`.  
   `segmentPushFrequency` is the frequency of uploading new created / updated segments to Pinot cluster.
   `APPEND` use case is that the segment to be uploaded is brand new and it's just added to the previous set of segments. Thus the number of segments for that table in the cluster will be increased.
   `REFRESH` use case is that the segment to be uploaded is updated from a previous segment and will replace the previous segment in the pinot cluster. The number of segments for that table remains the same.
