Is it possible to send difference of live traffic data each time?

[safe-bug]

Hello

I want to know is it possible to send the difference of live traffic data (csv) in each cycle when I want to update the graph speeds?

Currently I have to update around 50 million edges on each traffic update cycle but actually a small number of these edges speed is changing in each cycle so if it's possible I can customize a much more small csv and save time.

I had some tests and it seems that when I don't provide other edges speeds the last valid value isn't kept. Is there any way to make it possible?

Thanks
