OTEL as a set of standards is admirable and ambitious, though in my experience actual implementation differs significantly between different vendors and they all seem to overcomplicate it.

Plus that tens of terabytes of data you have to store for a week worth of traces

That's why you sample just enough instead of storing everything

Sampling unconditionally at the start of the request is worth less than sampling at the end (so that your sample 1% of successful traces and be 100% of traces with issues).
