Vitess tablets in its cell. This enables a cell to be taken down and rebuilt as a unit. Vitess limits cross-cell traffic for both data and metadata. While it may be useful to also have the ability to route traffic to individual cells, Vitess currently serves reads only from the local cell. Writes will go cross-cell when necessary, to wherever the master for that shard resides. Keyspace Graph The keyspace validation procedures. You could do in-tablet integrity checks to verify foreign-key-like relationships or cross-shard integrity checks if, for example, an index table in one keyspace references data in another

the web ui and the VTAdmin-api. Once a request has been authenticated and authorized, it will not cross any further trust boundaries. The requests made by VTAdmin-Web are unauthenticated and unauthorized does not escape the parameters to the template. Vitess could be exposed to front-end attacks such as cross-site scripting, if an attacker manages to pass valid javascript into the templates. Ada Logics found practices, and VTAdmin-web is written with React which is hardened to defend against many cases of Cross-Site Scripting. The backend, VTAdmin-api, is written in Go which is a memory-safe language. The VTAdmin
