Note that the gRPC behavior is in Beta and has limited functionality.

This behavior enables support for Google Remote Procedure Call (gRPC). gRPC is an open-source, high-performance RPC framework that uses protocol buffers (protobuf) to transmit data. Protobuf messages are small, fast, and support large amounts of programming libraries and tooling.

You can use gRPC to enable function calls across processes and connect large numbers of microservices. It's built on HTTP/2, supports multiplexed streams, and four communication patterns: request-response, server streaming, client streaming, and bidirectional streaming.
