Fast DDS introduces a new feature to get more efficiency and flexibility. The new participant property allows developers to fine-tune the discovery phase by leveraging the Shared Memory (SHM) Transport metatraffic behavior.
Let's go into the details:
By default, the SHM transport behaves swiftly during the discovery phase. While participant discovery utilizes UDP multicast, endpoint discovery employs UDP unicast. However, with the latest feature, developers can change these defaults to use shared memory for both discovery scenarios.
Want to know a use case?
Consider this: When a participant only relies on SHM transport, it might fail to discover other participants using UDP and SHM. By enabling SHM multicast discovery, users unlock seamless discovery capabilities. Alternatively, enabling SHM unicast discovery can expedite discovery processes within the same machine.
Developers can customize this behavior to fit their specific requirements using an XML file ((XML Profiles) or the C++ API.
