VReplication Command Reference

VReplication has both high-level and low-level commands that let you work with VReplication workflows. These commands are run by Vitess' administration tool: vtctld.

vtctl is a command-line tool used to administer a Vitess cluster. It is available as both a standalone tool (vtctl) and client-server (vtctlclient in combination with vtctld). Using client-server is recommended, as it provides an additional layer of security when using the client remotely.

A list of some common commands follows. Some commands contain a -dry_run will reports on what the particular command will do without actually performing the action.
