Ballerina gRPC Library

The gRPC library is one of the standard library modules of the Ballerina language.

This provides support for the gRPC messaging protocol. gRPC is an inter-process communication technology that allows you to connect, invoke, and operate distributed, heterogeneous applications as easily as making a local function call. The gRPC protocol is layered over HTTP/2 and uses Protocol Buffers for marshaling/unmarshaling messages. This makes gRPC highly efficient on wire and a simple service definition framework.

This Library supports the messaging patterns below. For more information on the supported operations, go to the grpc module.

Simple RPC (Unary RPC)
Server streaming RPC
Client streaming RPC
Bidirectional Streaming RPC

For example demonstrations of the usage, go to Ballerina By Examples.
