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


The read/write splitting function has been enabled for the RDS instance. For more information, see Enable the read/write splitting function of an ApsaraDB RDS for MySQL instance.


  • 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.
