grpc 线程池管理

使用步骤

1. 引入下述依赖

   <dependency>
        <groupId>org.dromara.dynamictp</groupId>
        <artifactId>dynamic-tp-spring-boot-starter-adapter-grpc</artifactId>
        <version>1.1.4</version>
    </dependency>

2. 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
          runTimeout: 200                             
          queueTimeout: 100

3. 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. grpc 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
