Github user dawidwys commented on the issue: https://github.com/apache/flink/pull/3495 I do like you code, only thing missing I had in mind yesterday was an idea of defaultGroup, which is an easy way to group options with not overlapping prefixes e.g. right now in documentation (in doc files) of jobmanager we have options like jobmanager.* and blob.*. I modified a little bit your solution to enable the defaultGroup. What do you think of that idea?
