Connection test::RSSLConnection does not support optimized Pause/Resume. Optimized Pause/Resume requests will be converted to individual item Pause/Resume requests for this connection.
Pause and Resume feature helps to reduce the volume of data flowing across the network for items that are already streaming to the consumer application. You can pause item(data) streams e.g. when the data is not displayed for now. Then, resume the item streams when you want to display data again without close and open the streams.
Optimized Pause and Resume extends the existing Pause and Resume domain support to any domain (Refinitiv domain and customer defined domain).
The warning messages indicate that the server that the application connects to does not support Optimized Pause/Resume feature. Hence, RFA prints these warning messages after it receives this information from the server. If your application sends Optimized Pause/Resume requests, they will be converted to individual item Pause/Resume requests before sending to the server.
If you do not want to use Optimized Pause/Resume feature. You can ignore the warning messages because your application still work properly. Otherwise, you should contact the support team of the server to enable this feature.
