## What it is
JobRunr is a Java library for performing distributed background processing on the JVM using Java 8 lambdas, with jobs persisted in an existing SQL or NoSQL database. It supports fire-and-forget, delayed, scheduled, and recurring CRON jobs with automatic retries and a built-in monitoring dashboard.

## Use cases
- run background jobs in java
- schedule recurring cron jobs on the jvm
- replace quartz with a simpler scheduler
- process delayed tasks like sending emails after signup
- distribute job processing across multiple instances
- guarantee job execution survives application restarts
- offload cpu or io intensive work from request threads

## When to choose
- you want a dead-simple API for durable background jobs in Java with minimal dependencies
- you want jobs persisted in your existing Postgres, MySQL, or MongoDB database without extra infrastructure
- you need distributed execution across a cluster or Kubernetes with automatic retries and a dashboard
- you want a modern, actively maintained alternative to Quartz

## When to avoid
- you need more than 100 recurring jobs or features like priority queues, batches, and workflows without paying for JobRunr Pro
- your stack is not on the JVM
- you need a standalone message broker rather than a database-backed job scheduler
- LGPLv3 licensing is incompatible with your project's requirements
