Skillshub spring-boot-scheduling

Standards for scheduled tasks and distributed locking with ShedLock. Use when implementing @Scheduled tasks or distributed locking with ShedLock in Spring Boot. (triggers: **/*Scheduler.java, **/*Job.java, scheduled, shedlock, cron)

Spring Boot Scheduling Standards

Priority: P0

Implementation Guidelines

Scheduled Tasks

  • ThreadPool: ALWAYS configure a dedicated 
    TaskScheduler
    (default is 1 thread). Enable with 
    @EnableScheduling
    annotation.
  • Async: Keep 
    @Scheduled
    methods light; offload to 
    @Async
    /Queues. Wrap logic in try/catch; log errors and use 
    @Retryable
    for retry on transient failures.

Distributed Locking (ShedLock)

  • Problem: 
    @Scheduled
    runs on ALL pods in K8s.
  • Solution: Use ShedLock to guarantee single execution.
  • Config: Set 
    lockAtMostFor
    (deadlock safety) and 
    lockAtLeastFor
    (debounce).

Anti-Patterns

  • No Default Pool: Configure dedicated TaskScheduler (default is 1 thread).
  • No duplicates: Use ShedLock for distributed cron in multi-pod deployments.
  • No task state: Design tasks to be idempotent; assume pod can restart.
