ServiceMesh-7-新发展-Mesh Broker架构 服务消费者 中心化 Mesh Broker 服务提供 者 连接创建 连接创建 服务注册 • 无端口监听 • 占用资源少 • 无网络要求 • 无底层基础设施依赖：任何PaaS间可以通信 • 无服务注册依赖，无负载均衡需求 • 简化运维：中心化后，只需要管理服务器就可以了 • 业务异步化 缺点： 单点故障，需要提供高可用方案，如Broker部署在K8S中，HPA控

address these pain points: ● End-to-end : The test framework validates the end (client) to end (broker/exchange) algo behavior. ● Controlled external dependencies : All external dependencies

4+ 2+ 300G auto.create.topics.enable = true ：如果还没有创建 topic，Kafka 会在 broker 上自动创建 topic broker.id ：用来标识 Kafka 集群的必备参数，不能重复；如 broker.id = 1 fs.file-max = 1000000 ：Kafka 会使用大量文件和网络 socket，建议修改成 1000000，通过

Create an access key pair: • <broker_endpoint> • <broker_api_key> • <broker_api_secret> • • 819 • Kafka machine specified in the sink URI. In a production environment, a Kafka cluster has multiple broker nodes. Therefore, you can add the addresses of multiple brokers to the sink UIR. This ensures stable

From v5.0.6 and v4.0.6, the default value has changed from Parameter/Parameter value Description required-acks A parameter used in the Produce request, which notifies the broker of the number of replica acknowledgements it needs to receive before responding. Value options are the minimum number of replicated replicas using the min.insync.replicas configuration item of the broker).
