JobRunr - Easy Distributed Job Scheduling
summary
JobRunr is an embeddable Java library that turns Java 8 lambdas into persisted, distributed jobs stored as JSON in SQL or NoSQL (Postgres, Mongo, Dynamo, Redis beta), processed by BackgroundJobServer JVMs that scale in Kubernetes. It uses optimistic locking for single-worker execution, 10 retries with exponential backoff by default, and stores MDC for tracing. Version 5.x adds supports Spring Native and reflection hints. The demo builds an uptime-robot clone with the dashboard, live logs and requeue working; the project reports ~30,000 Maven downloads per month.
