vtctl
vtctl Command Index
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.
Note that wherever vtctl
commands produced master or MASTER for tablet type, they now produce primary or PRIMARY. Scripts and tools that depend on parsing command output will need to be updated.
