You can switch the read/write splitting address type based on business scenarios. When you enable the read/write splitting function, the read/write splitting intranet address is generated by default. This article introduces how to switch between the intranet and Internet addresses of read/write splitting.


The read/write splitting function is enabled. For more information, see Enable read/write splitting.


When switching the address type, the master instance is subject to a transient disconnection of up to 30 seconds. To avoid the influence of transient disconnection, we recommend that you switch the network type during off-peak hours and make sure that automatic reconnection is available for your application.
