mysql vertical sub-table, horizontal sub-table program Vitess

Vitess is a database solution for deploying, expanding and managing large clusters of MySQL instances. It is architecturally able to run in public or private cloud architectures as efficiently as on dedicated hardware. It combines the scalability of NoSQL databases and extends many important MySQL functions. Vitess can help you solve the following problems:

1. Scale up by allowing you to shard the MySQL database while minimizing application changes.
2. Migrate from bare metal to private or public cloud.
3. Deploy and manage a large number of MySQL instances.

Vitess includes compatible JDBC and Go database drivers that use native query protocols. In addition, it implements the MySQL server protocol, which is actually compatible with any other language.

Since 2011, Vitess has been providing services for all YouTube database traffic, and has now been adopted by many companies to meet their production needs.
