Unforeseen use case of my GTID work: replicating from AWS Aurora to Google CloudSQL

A colleague brought an article to my attention.  I did not see it on Planet MySQL where I get most of the MySQL news (or it did not catch my eye there).  As it is interesting replication stuff, I think it is important to bring it to the attention of the MySQL Community, so I am writing this short post.

The surprising part for me is that it uses my 4-year-old work for online migration to GTID with MySQL 5.6.  This is a completely unforeseen use case of my work as I never thought that my hack would be useful after Oracle include an online migration path to GTID in MySQL 5.7 (Percona did something similar for MySQL 5.6).
