Hi,

I think there are two no-interpolation philosophy :
A : If the point is missing, you set 0
B : if the point is missing, don't add point

For sum or max aggregate, no difference. But for avg/min/dev, result will be different.

The A method is for continus metrics where no remote point as same as zero.
The B method is for stats metrics created with event and no point is lack event.

I think it's interesting to offer three options : interpolationToZero (method A), noInterpolation (method B - by default ?) and with-Interpolation (current option).

Regards.
