dc3-common-thread is the shared thread pool configuration module of the IoT DC3 platform. It configures the platform-wide async task executor used for @Async annotated methods across all services.

Module Information

Group ID: io.github.pnoker
Artifact ID: dc3-common-thread
Version: 2026.5.18

Key Components

Component	Purpose
`ThreadPoolConfig`	Creates and configures the `TaskExecutor` bean used by Spring's `@Async`
`ThreadProperties`	Binds thread pool properties from YAML (`core-pool-size`, `max-pool-size`, `queue-capacity`, etc.)
`ThreadInitRunner`	Startup log for confirming thread pool initialization

Configuration Properties

thread:
  pool:
    core-pool-size: ${THREAD_POOL_CORE_SIZE:10}
    max-pool-size: ${THREAD_POOL_MAX_SIZE:200}
    queue-capacity: ${THREAD_POOL_QUEUE_CAPACITY:1000}
    keep-alive-seconds: ${THREAD_POOL_KEEP_ALIVE:30}
    thread-name-prefix: dc3-async-

Usage

Any @Async annotated method (e.g., MetadataEventListener.onApplicationEvent) executes on this thread pool automatically when dc3-common-thread is on the classpath.
