PlanetScale addresses concerns about Vitess' reliability and data loss by debunking common myths. Vitess uses MySQL's lossless semi-synchronous replication feature to prevent data loss in case of master failure, and its control plane includes automated workflows for self-recovery. While some manual intervention is required in cases of network partition, the system is designed to optimize performance while ensuring high availability. PlanetScale offers resources such as a Slack community, quickstart guide, and open-sourced Kubernetes operator to help users learn more about Vitess and its capabilities.
