OpenTSDB interval sampling method

[Wang Liu]

Hello,all

    Does OpenTSDB have the feature of the interval sampling method?

    For example, only two data points are now collected, the time difference is one minute, but a function can be calculated every 5 seconds of time and value, and returned to the user.In other words, the sampling frequency can be increased by calculation.

If you asked for a 5s down sampling it would interpolate the values between the actual data the return 5s intervals.

hi, I tried to set 5s down sampling, but there is no extra point return, and I used version 2.3. 

Could I use two point`s rate and value to calculate the interval value., but it is too complex. I want to get blue point as follow picture.

Ah, you're looking for a LERPing downsampler but unfortunately we don't have that right now. Would you mind adding a feature request in Github please? thanks.
