Hi [~ste...@apache.org]. I have a prototype patch sitting around somewhere
which implements authoritative listings for DynamoDB. The solution is more
complex than the original description here implies, so we should either rename
this jira or create a new one.
Whichever JIRA we use, it should go in a Phase II umbrella for post-merge work.
