> In Hadoop, there are annotations that describe the visibility of an API and 
> its compatibility story:
> {noformat:title=https://github.com/apache/hadoop/blob/branch-2.6/hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/org/apache/hadoop/mapreduce/Job.java#L76}
> @InterfaceAudience.Public
> @InterfaceStability.Evolving
> {noformat}
> It would be nice to use some thing similar to this (if not the same thing) 
> and define our own (or same) compatibility story.
> This lock down the connector APIs and define a better contract about what can 
> be modified.
