   @mmcgowan can you provide more info of what you are after?
   
   At time of ingestion you create an approxHistogramFold, you can then create 
metrics based on that histogram in superset.
   
   in ingestion schema:
               { "type" : "approxHistogramFold", "name" : "hist_response_time", 
"fieldName" : "response_time", "resolution" : 50},
   
   metric json spec:
   { "type" : "quantile", "name" : "hist_response_time", "fieldName" : 
"hist_response_time",
     "probability" : 0.95 }
