Connection Pooling & Channel Reuse
Maximize gRPC throughput by reusing channels and managing connection pools, avoiding the cost of creating a new connection per request.
The Cost of New Connections
Opening a connection means a TCP handshake plus a TLS handshake — multiple round trips. Doing this per request destroys performance.
gRPC is built to reuse long-lived connections instead.
Channels Multiplex Streams
A gRPC channel wraps an HTTP/2 connection. HTTP/2 multiplexes many concurrent streams (RPCs) over a single connection, so one channel can serve thousands of calls.
