I would like to discuss a generalized data "temperature"

Is data available that shows the effectiveness of this approach and
that compares this approach with existing approaches?
Yes, I did the benchmarking. I can see the quantitative estimation of
files' temperature.
What has been measured in these benchmarks?
Which existing approaches would you like to compare?
F2FS has a built-in algorithm for assigning data temperatures.
And what could we imply by effectiveness of the approach? Do you have
a vision how we can estimate the effectiveness? :)
Isn't the goal of providing data temperature information to the device
to reduce write amplification (W.A.)? I think that W.A. data would be
useful but I'm not sure whether such data is easy to extract from a
storage device.
Thanks,
Bart.
