gRPC 1.10.0 已正式发布，该版本包含了大量改进和 bug 修复，具体如下：

Core

• To provide a cleaner install with fewer public headers, several features of core have been removed from the surface or GPR API as they were not used in any wrapped language (except C++) or in external applications, such as:
  a. grpc_alarm (removed; the C++ grpc::Alarm now directly invokes core subsurface functions)
  b. gpr_join_host_port, gpr_cmdline, gpr_subprocess (moved to test/core/util)
  c. gpr_tls, gpr_avl (internalized)
  d. gpr_thd (internalized)

• Except gpr_thd_id and gpr_thd_currentid, which remain public

• As a result of these changes, core is now at version 6.0.0

• Fix memory leaks in max_age_filter (#14501) and http_proxy (#14137)

• Changed resolver and LB policy APIs to C++

• Added re-resolution into grpclb policy (#14438).

• Extracted per LB-call data from grpclb policy (#13911)

• Fixed C-core to immediately take ownership of slices when a send_message op is started

• Fix a race condition causing freeze at shutdown with epollex polling strategy (#14177)

• Improvements in CMake: find_package (#14353)

• Portability fixes (#14136, #14198)

• Test infrastructure cleanup (#14117)

• Update BoringSSL submodule (#13948)

• Make RR re-resolve when any of its subchannels fail (#14170)

• DNS resolver caches results, allowing it to be hit arbitrarily often. Resolution frequency is controlled via channel arg GRPC_ARG_DNS_MIN_TIME_BETWEEN_RESOLUTIONS_MS. (#14228)

gRPC 是一个高性能、开源、通用的 RPC 框架，面向移动和 HTTP/2 设计，是由谷歌发布的首款基于 Protocol Buffers 的 RPC 框架。目前提供 C、 Java 和 Go 语言版本，分别是：grpc, grpc-java, grpc-go. 其中 C 版本支持 C, C++, Node.js, Python, Ruby, Objective-C, PHP 和 C#。

gRPC 基于 HTTP/2 标准设计，带来诸如双向流、流控、头部压缩、单 TCP 连接上的多复用请求等特性。这些特性使得其在移动设备上表现更好，更省电且节省空间占用。

服务接口定义示例：

message HelloRequest {
  string greeting = 1;
}

message HelloResponse {
  string reply = 1;
}

service HelloService {
  rpc SayHello(HelloRequest) returns (HelloResponse);
}
