When MemSQL is configured for synchronous durability and all databases are configured with synchronous replication, Jepsen confirms that writes to MemSQL are durable and acknowledged appropriately. As part of testing for the 4.0 release, we used the jepsen network partition test and observed data durability equivalent to Postgres(https://aphyr.com/posts/282-call-me-maybe-postgres) e.g. the scalability of a cluster with the durability of a single node machine. As part of running this test, we noticed some opportunities to do some cool performance optimizations. Stay tuned for a blog post to follow!
