I don't think you need this either.

Please use the updated license headers:

This should be defined as a Duration. You can set a min and max using @DurationMin and @DurationMax.

I wonder if this is the right way to go. Why would somebody need to configure this path? I think ideally, this is part of the data-prepper directory structure and is automatically defined.

I don't think there is any value to using these constants. Just put the literal value in the @JsonProperty. Some older implementations did this to support migration from legacy concepts.
