It is possible to deploy a connector that has been configured to provide read-only access to the underlying databases on the standard port. This enforces read-only connectivity through this connector, regardless of any session or connector configuration options. This can be useful for a standalone connector, or a single connector within a dataservice.

This setting places the connector into RO_RELAXED mode. The connector will choose the Primary if there is no available Replica. See Section 7.4.2, “Primary/Replica Selection” for more detail on Quality of Service modes.

To enable this functionality, configure the connector using the --connector-readonly option:

shell> tpm configure alpha --connector-readonly=true

To enable this functionality on specific hosts only, add the --hosts option:

shell> tpm configure alpha --connector-readonly=true --hosts=host1,host3
