PolarDB-X 1.0 allows you to switch zones for instances. You can switch the zone of a PolarDB-X 1.0 instance if an inappropriate zone is selected for the instance or the quota in the original zone is insufficient.
Note
Typically, it takes about one to two minutes to switch zones. We recommend that you switch zones during off-peak hours to avoid business interruptions.
A transient disconnection within seconds may occur when you switch zones. Make sure that your application client supports automatic reconnection.
