Introduction to DynamicTp

DynamicTp is a lightweight dynamic thread pool monitoring and management tool based on the configuration center. Its main functions can be summarized into several categories, such as dynamic parameter adjustment, notification and alarm, operation monitoring, and third-party package thread pool management.

After several iterations, the latest version v1.1.2 has the following features

  • code zero intrusion: We have changed the previous usage posture of the thread pool. All configurations are placed in the configuration center. When the service is started, the configuration will be pulled from the configuration center to generate a thread pool object and placed in the Spring container. When using it, it will be directly obtained from the Spring container. code zero intrusion

  • notification alarm: Provides multiple alarm dimensions (configuration change notification, activity alarm, capacity threshold alarm, rejection trigger alarm, task execution or waiting timeout alarm), supports enterprise WeChat, DingTalk, Feishu, and email alarms, and provides an SPI interface to automatically Define extension implementation

  • Operation monitoring: Timely collection of thread pool indicator data, supports three ways of MicroMeter, JsonLog log output, and Endpoint, and can be realized through custom extensions of the SPI interface

  • task enhancement: Provide task packaging function, just implement the TaskWrapper interface, such as MdcTaskWrapper, TtlTaskWrapper, SwTraceTaskWrapper, which can support thread pool context information transfer

  • Multi-configuration center support: Realize dynamic adjustment of thread pool parameters based on the mainstream configuration center, which takes effect in real time, supports Nacos, Apollo, Zookeeper, Consul, Etcd, Polaris, ServiceComb, and also provides SPI interface for custom extension implementation

  • Middleware thread pool management: Integrated management of thread pools of commonly used third-party components, has integrated thread pool management of components such as Tomcat, Jetty, Undertow, Dubbo, RocketMq, Hystrix, Grpc, Motan, Okhttp3, Brpc, Tars, SofaRpc, RabbitMq (parameter adjustment, monitoring and alarming) )

  • lightweight and simple: Based on the implementation of SpringBoot, the starter is introduced, and the access can be completed in only 4 simple steps, and it can be completed in 3 minutes.

  • multimodal: Refer to the Tomcat thread pool to provide the EagerDtpExecutor thread pool used in IO-intensive scenarios

  • compatibility: JUC ordinary thread pool and ThreadPoolTaskExecutor in Spring can also be monitored by the framework, just add @DynamicTp annotation when @Bean is defined

  • reliability: The thread pool provided by the framework implements the Spring life cycle method, which can process as many tasks in the queue as possible before the Spring container is closed

  • Highly scalable: The core functions of the framework provide SPI interface for user-defined personalized implementation (configuration center, configuration file parsing, notification alarm, monitoring data collection, task packaging, etc.)

  • Large-scale online application: Referring to the practice of Meituan’s thread pool, Meituan already has mature application experience of this theory
