gRPC allows to run multiple gRPC services on the same gRPC server, as well as use the same gRPC client connection for multiple gRPC client stubs.
Tip
One powerful use for gRPC multiplexing in a microservice architecture is to host multiple major versions of the same service in one server process. This allows a service to accommodate legacy clients after a breaking API change. Once the old version of the service contract is no longer in use, it can be removed from the server.
Use Cases
- Hosting related services on the same server (e.g.,
OrderManagementandGreeter). - Reducing connection overhead by reusing a single client connection.
- Supporting multiple API versions of the same service on one server.
