// or batch your historical data by time, then reduce per batch period.

sub historical_points() {
  emit -from :0: -limit 10 
  | put value = count()
}
historical_points 
| reduce sum(value) 
| view table -title "Historical sum total"
;
historical_points 
| batch 5 
| reduce sum(value) 
| view table
    -update "append" 
    -title "Historical 5-second subtotals"
;

// On live streaming data, you must batch by time, then reduce per batch period.

sub live_points() {
  emit -limit 10 
  | put value = count()
}
live_points 
| batch 3 
| reduce sum(value)
