Deterministic Sampling
A sampling method in which decisions are derived by mapping a stable property of a request, such as its request ID, through a hash function rather than relying on the state of a random number generator. The same request therefore always receives the same sampling outcome, which facilitates debugging and regression comparison across runs.

The core of deterministic sampling is that the sampling decision does not depend on the state of a random number generator, but is determined by mapping a stable property of the request (such as the request ID) through a hash function, so the same request yields the same result no matter how many times it is rerun.
