we have a production application that depends on some business parameters such as thresholds, tax-rates, VAT etc. these parameters are subject to changes from time to time.
Therefore - we don't want to hard-code them but rather have them configured at some kind of parameter-storage change system so that they can be changed on-the-fly without involving development and code-deployemnts.
also, this application constantly runs regression tests against old payments on which we assert the results matches. ideally we would like to store these parameters' values with their time-point so that when the application fetches these parameters for an old payment it picks the parameter that was valid at the time of the original calculation
is there any know parameter-as-a-service that supports that? (I noticed that while aws's parameter-store supports versioning, for example, supports time-points, it is and far from being elegant and requires cumbersome adaptations)
thanks in advance
