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. View the list of adopters.
Reporting a Problem, Issue, or Bug
To report a problem, create a GitHub issue.
For topics that are better discussed live, please join the Vitess Slack workspace. You may post any questions on the #general channel or join some of the special-interest channels.
Follow Vitess Blog for low-frequency updates like new features and releases.

Overview ¶
test.go is a "Go script" for running Vitess tests. It runs each test in its own Docker container for hermeticity and (potentially) parallelism. If a test fails, this script will save the output in _test/ and continue with other tests.
Before using it, you should have Docker 1.5+ installed, and have your user in the group that lets you run the docker command without sudo. The first time you run against a given flavor, it may take some time for the corresponding bootstrap image (vitess/bootstrap:<flavor>) to be downloaded.
It is meant to be run from the Vitess root, like so:
$ go run test.go [args]
For a list of options, run:
$ go run test.go --help
