Vitess is a database clustering system for horizontal scaling of MySQL
PerformanceVitess automatically rewrites queries that hurt database performance. It also uses caching mechanisms to mediate queries and prevent duplicate queries from simultaneously reaching your database.
ManageabilityVitess automatically handles functions like master failovers and backups. It uses a lock server to track and administer servers, letting your application be blissfully ignorant of database topology.
Connection poolingVitess eliminates the high-memory overhead of MySQL connections. Vitess servers easily handle thousands of connections at once.
Shard managementMySQL doesn’t natively support sharding, but you will likely need it as your database grows. Vitess saves you from having to add sharding logic to your app and also enables live resharding with minimal read-only downtime.
WorkflowVitess keeps track of all of the metadata about your cluster configuration so that the cluster view is always up-to-date and consistent for different clients.
