This topic describes how to disable read/write splitting for an RDS MySQL instance.

This topic applies only to RDS instances that run in shared proxy mode. For more information about RDS instances that run in dedicated proxy mode, see What are dedicated proxies.


The read/write splitting function has been enabled for the RDS instance. For more information, see Enable the read/write splitting feature for an ApsaraDB RDS for MySQL instance (shared proxy).


  • When the read/write splitting function is being disabled, the RDS instance is disconnected for 30 seconds or less. We recommend that you disable this function during off-peak hours and make sure that your application can automatically reconnect to the RDS instance.
  • After the read/write splitting function is disabled, the read/write splitting address becomes invalid. Make sure that your application no longer uses the read/write splitting address to connect to the RDS instance.
