------------------------------------------------------------

The guarantee provided by the same city multi-data center solution is that in the event of any data center failure, the cluster can automatically recover service without manual intervention, and can ensure data consistency. Note that in the event of a failure, the scheduling mechanism always prioritizes availability over performance first.
