I doubt that this will slow down the summarizer performance because you add
sum statistics internally (and this sum value will possible to overflow).
We can directly use `count * mean` to get the sum if we want to use it.--- --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
