This is a follow-up post in the MySQL Master Replication Crash Safety series. In the previous posts, we explored the consequences of reducing durability on masters (different data inconsistencies after an OS crash depending on replication type) and the performance boost associated with this configuration (benchmark results done on Google Cloud Platform / GCP). The consequences are summarised in the introduction of Part #4, and the tests are the subject of this last post. Also in this last post, I mentioned that my results for high durability are limited by the sync latencies of GCP persistent disks. As I found a system with better latencies, I am able to present new results. And this system is a vm in Amazon Web Services (AWS) with local SSD.
