If the read/write splitting function is no longer needed, you can disable it. The read/write splitting function can only be used when at least one read-only instance is available, so you must disable the read/write splitting function before you delete the last available read-only instance. Otherwise, the instance cannot be deleted.
This document explains how to disable the read/write splitting function.
|After the read/write splitting function is disabled, your applications cannot connect to the read/write splitting address any longer. Make sure that your database connection configuration does not include this connection address.|
