Bidirectional Streaming
Deep dive into gRPC bidirectional streaming with the SubscribeNotifications example, connection lifecycle, and dynamic filter updates.
Bidirectional streaming is gRPC's most advanced pattern. Both the client and server send independent streams of messages over a single connection. Messages can be sent in any order - the client does not need to wait for a server response before sending another message, and vice versa.
How It Works
The client opens a connection and both sides begin streaming. Either side can send messages at any time. The stream ends when either side signals completion. For long-lived connections like event subscriptions, the server may send heartbeat messages to keep the connection alive.
SubscribeNotifications - Dynamic Event Subscriptions
The notification service demonstrates a real-world bidirectional streaming pattern. Clients subscribe to events and can dynamically update their filters without reconnecting.
