the VTTablet. vtctl vtctl is a command-line tool used to administer a Vitess cluster. It allows a human or application to easily interact with a Vitess implementation. Using vtctl, you can identify master mind: • Enable simple updates that propagate to your entire fleet of servers. • Require minimal human interaction. • Minimize errors by testing changes against a temporary database. • Guarantee very little system. Generally, we don’t expect the errors to go away by themselves, but they may go away after human intervention. Examples of scenarios where INTERNAL_ERROR is returned: 1. Something is not configured
