gRPC Python thread_pool vs max_concurrent_rpcs

阅读更多关于 gRPC Python thread_pool vs max_concurrent_rpcs

问题 When launching a Python grpc.server , what's the difference between maximum_concurrent_rpcs and the max_workers used in the thread pool. If I want maximum_concurrent_rpcs=1 , should I still provide more than one thread to the thread pool? In other words, should I match maximum_concurrent_rpcs to my max_workers , or should I provide more workers than max concurrent RPCs? server = grpc.server( thread_pool=futures.ThreadPoolExecutor(max_workers=1), maximum_concurrent_rpcs=1, ) 回答1: If your

How to pass data from grpc rpc call to server interceptor in java

阅读更多关于 How to pass data from grpc rpc call to server interceptor in java

问题 I am trying to set some metadata with a value from the response after the rpc server call has been processed. The plan was to use server interceptor and override close method. Something like this: https://github.com/dconnelly/grpc-error-example/blob/master/src/main/java/example/Errors.java#L38 Since the metadata value depends on the response, I need some way to pass data from rpc server call to server interceptor or access the response from interceptor In Golang, the metadata can be set

点击上方“ JavaEdge ”，关注公众号设为“ 星标 ”，好文章不错过！ RPC框架主要组成通信框架通信协议序列化和反序列化格式 1 分类 RPC框架主要分为： 1.1 绑定语言平台 1.1.1 Dubbo 国内最早开源的RPC框架，由阿里巴巴公司开发并于2011年末对外开源，仅支持Java 架构 Consumer 服务消费者 Provider 服务提供者 Registry 注册中心 Monitor是监控系统交互流程 Consumer 通过 Registry 获取到 Provider 节点再通过Dubbo的客户端SDK与Provider建立连接，并发起调用 Provider 通过Dubbo的服务端SDK接收到 Consumer 请求处理后再把结果返回给Consumer 服务消费者、提供者都需引入Dubbo的SDK才来完成RPC调用，因为Dubbo是用Java实现，所以要求服务消费者、提供者也都必须用Java。主要实现默认采用Netty作为通信框架除了支持私有的Dubbo协议外，还支持RMI、Hession、HTTP、Thrift 支持多种序列化格式，比如Dubbo、Hession、JSON、Kryo、FST 1.1.2 Motan 微博内部使用的RPC框架，于2016年对外开源，仅支持Java。架构与Dubbo类似，都要在Client端（服务消费者
