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


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


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