grpc 线程池管理

使用步骤

  1. 引入下述依赖
   <dependency>
        <groupId>cn.dynamictp</groupId>
        <artifactId>dynamic-tp-spring-boot-starter-adapter-grpc</artifactId>
        <version>1.1.2</version>
    </dependency>
  1. 配置文件中配置 grpc 线程池
spring:
  dynamic:
    tp:
      enabled: true
      enabledCollect: true          # 是否开启监控指标采集,默认false
      collectorTypes: micrometer    # 监控数据采集器类型(logging | micrometer | internal_logging),默认micrometer
      monitorInterval: 5            # 监控时间间隔(报警判断、指标采集),默认5s
      grpcTp:                                      # grpc 线程池配置
        - threadPoolName: shadedNettyTp
          corePoolSize: 100
          maximumPoolSize: 200
          keepAliveTime: 60
  1. 启动日志

服务启动看到有如下日志输出说明接入成功,如果开启了通知,同时会推送参数修改通知

DynamicTp adapter, grpc server executors init end, executors: {shadedNettyTp=ExecutorWrapper(threadPoolName=shadedNettyTp, executor=java.util.concurrent.ThreadPoolExecutor@176b7d8[Running, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0], threadPoolAliasName=null, notifyItems=[NotifyItem(platforms=null, enabled=true, type=liveness, threshold=70, interval=120, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=change, threshold=0, interval=1, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=capacity, threshold=70, interval=120, clusterLimit=1)], notifyEnabled=true), inProcessTp=ExecutorWrapper(threadPoolName=inProcessTp, executor=java.util.concurrent.ThreadPoolExecutor@176b7d8[Running, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0], threadPoolAliasName=null, notifyItems=[NotifyItem(platforms=null, enabled=true, type=liveness, threshold=70, interval=120, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=change, threshold=0, interval=1, clusterLimit=1), NotifyItem(platforms=null, enabled=true, type=capacity, threshold=70, interval=120, clusterLimit=1)], notifyEnabled=true)}
DynamicTp grpcTp adapter, [shadedNettyTp] refreshed end, changed keys: [corePoolSize, maxPoolSize], corePoolSize: [0 => 100], maxPoolSize: [2147483647 => 200], keepAliveTime: [60 => 60]

提示

  1. grpc 官方没有提供 springboot starter,我们对开源项目 https://github.com/yidongnan/grpc-spring-boot-starter 进行了适配,该项目也是 star 最多最活跃的 grpc springboot starter
  2. 线程池名称规则,基于上述项目提供的三种模式 shadedNettyGrpcServerLifecycle / inProcessGrpcServerLifecycle / nettyGrpcServerLifecycle,分别对应 shadedNettyTp / inProcessTp / nettyTp 三个名称(可以在启动日志找输出的线程池名称)
  3. hystrix 线程池享有动态调参、监控、通知告警完整的功能
  4. grpc 线程池通知告警项有(调参通知、活性告警、队列容量告警),可通过 notifyItems 自定义配置项值,默认全部开启
  5. 只支持 server 端线程池管理
