Doubt regarding BackPressure

Hi,

I was running some topologies with BackPressure ON.

Can anybody please tell me the reason behind the default values of high and
low watermarks, as 0.9 and 0.4 respectively.

I am observing failures with 0.9, and less number of failures with 0.7 as
high watermark.

Thanks already.
