production environment, there should be 3-5 etcd replicas. The number of VTGate servers will need to scale up based on cluster size. • mysqlProtocol.authType is set to none. This should be changed to secret scratch, your first step with Vitess would be to define your database topology. However, if you need to scale your existing database, you’d likely start by deploying a connection proxy. Vitess tools and servers are designed to help you whether you start with a complete fleet of databases or start small and scale over time. For smaller implementations, vttablet features like connection pooling and query rewriting

Compatibility Vitess is being used to power many mission-critical production workloads at very large scale. Moreover, many users deploy directly from the main branch. It is very important the changes made multi-schema by requiring the user to launch one vttablet process per schema. This, however, does not scale for the number of schemas we are beginning to see. To enable this, we need the ability for a single links working. • A better way to specify flags: the existing approach of command line flags may not scale. • A tablet manager that can represent multiple tablet ids. Other parts of TabletServer have already
