= Vert.x gRPC

The best description of gRPC can be seen at wikipedia.

[quote, wikipedia, wikipedia]
____
gRPC is an open source remote procedure call (RPC) system initially developed at Google. It uses HTTP/2 for
transport, Protocol Buffers as the interface description language, and provides features such as authentication,
bidirectional streaming and flow control, blocking or nonblocking bindings, and cancellation and timeouts. It
generates cross-platform client and server bindings for many languages.

Vert.x gRPC is a module that will align the programming style of Google gRPC with Vert.x style. As a user of this
module you will be more familiar with the code style using Vert.x Streams and Futures while benefiting from all the
benefits of gRPC.

For more information related to gRPC please consult the official documentation site http://www.grpc.io/.

WARNING: Since Vert.x 4.3, this module is the new support for gRPC in the Vert.x stack, the previous implementation based
on gRPC Netty is still available and has been renamed Vert.x gRPC Netty, it can be found at https://vertx.io/docs/vertx-grpc-netty/java/ .
This module has _Tech Preview_ status, this means the API can change between versions.

Vert.x gRPC is split in two parts

- Vert.x gRPC Server
- Vert.x gRPC Client
