Question

When using gRPC, which mechanism allows a single TCP connection to handle multiple concurrent requests without waiting for the previous response?

Accepted Answer

The mechanism that enables a single TCP connection to handle multiple concurrent requests is HTTP/2 multiplexing. In traditional HTTP/1.1, a client must wait for a server to send a response to one request before sending the next one, which creates a bottleneck. HTTP/2 solves this by breaking down data into small units called frames. Each request and response is assigned a unique stream identifier, which allows these frames to be interleaved or mixed together on the same physical TCP connection. Because each frame carries an ID that tells the receiver which request or response it belongs to, the server can process multiple operations in parallel and reconstruct the original data streams at the destination. This process eliminates the need to open multiple TCP connections, thereby reducing network latency and resource consumption.
