Vitess
Vitess is a database clustering system for horizontal scaling of MySQL through generalized sharding.
By encapsulating shard-routing logic, Vitess allows application code and database queries to remain agnostic to the distribution of data onto multiple shards. With Vitess, you can even split and merge shards as your needs grow, with an atomic cutover step that takes only a few seconds.
Vitess has been a core component of YouTube's database infrastructure since 2011, and has grown to encompass tens of thousands of MySQL nodes.
For more about Vitess, please visit vitess.io.
Vitess has a growing community. You can view the list of adopters here.
Dolt's Use of Vitess
Dolt's fork of Vitess has headed in a different direction from the main project. In addition to adding support for DDL statements, stored procedures, and triggers (never a priority of the Vitess project), Dolt's fork prunes away the 90% of Vitess that isn't vital to Dolt's current roadmap as a version controlled database. You can read details about this work in this blog post.
