Hi,
is not it a problem to use LittleEndian and BigEndian on SpanID?
see:
Hi @euskadi31, welcome to the forum 
Keen eyes! The difference in endianness is not a problem.
In the first two cases we're just generating some random bytes, and it's been a while, but I think this was just the most efficient way to do it. In the sampler we're just interested in knowing whether the span ID, when converted to a number, is less than a predetermined value. They don't need to be consistent with each other.
ok, Thank you for your explanation
