Hi All,
I have recently started looking into utilising read only routing to offload some of the reporting load for some databases. I have the AG with appropriate read intent set and can connect to the secondary read intent DB with no issues. The issue I am facing is how to resource govern the re-directed read only connection.
My existing classifier function governs based on the VIP and the 'local net address' of the incoming connection. But when I have set up the read only routing lists I have to specify the actual SQL Server Host ip and port, not the VIP and port and the classifier function does not pick up the connection and leaves it in the default resource group.
I guess I need to know if its possible to pick up within a classifier function that the re-directed connection is a re-directed connection - ie a read-intent only secondary db connection.
Any thoughts on if and how this could be achieved?
