Example Usage Managed MySQL In this mode, Vitess actively manages MySQL: export TOPOLOGY_FLAGS="-topo_implementation etcd2 -topo_global_server_address localhost:2379 -topo_global_root

the attack surface minimal and selecting the language suited for this implementation. The auditors managed to reach wide-spanning coverage of all aspects pertinent to the main repository of the Vitess software
