DynamicTp – A Java Dynamic ThreadPool Framework for Runtime Configuration, Monitoring, and Alerting

DynamicTp is a Java‑based dynamic thread‑pool framework that extends ThreadPoolExecutor to allow runtime parameter adjustment, real‑time monitoring, and alerting.

It solves three common pain points: difficulty determining optimal core parameters, the need to redeploy services after manual changes, and the lack of visibility into thread‑pool health.

Background : Most microservice projects use distributed configuration centers (Nacos, Apollo, Zookeeper, Consul, Etcd) that can push dynamic changes, making them ideal for dynamic thread‑pool tuning.

Key features include zero‑intrusion configuration via a configuration center, a lightweight SpringBoot starter, high extensibility through SPI, support for multiple alert channels (DingTalk, WeChat, Feishu, email), and integration with monitoring tools such as MicroMeter, Grafana, JsonLog, and custom Endpoint.

Architecture is divided into modules: adapter (third‑party component pools), common , core (dynamic adjustment, monitoring, alerts), example , extension (Redis flow‑control, mail, SkyWalking), logging , and starter .

The framework provides five functional modules: configuration change listening, internal thread‑pool management, third‑party component pool management, monitoring, and notification/alerting.

Supported configuration centers: Nacos , Apollo , Zookeeper , Consul , Etcd . Supported third‑party pools include Tomcat, Jetty, Undertow, Dubbo, RocketMQ, Hystrix, gRPC, etc.
