Quartz is a richly featured, open-source job scheduling library for Java applications, supporting simple to complex schedules for thousands of jobs. It offers enterprise features such as JTA transaction support and clustering.

Use cases

• run cron jobs in a Java application
• schedule background tasks with clustering
• execute recurring jobs in an e-commerce system
• trigger jobs at specific times or intervals
• manage thousands of scheduled jobs with persistence

When to choose

• you need robust job scheduling embedded in a Java/JVM application
• you need clustering and failover for scheduled jobs
• you need cron-like or complex trigger schedules with persistent job stores

When to avoid

• you need distributed task queues outside the JVM ecosystem
• you only need simple in-process timers provided by your language runtime
• you want a standalone scheduler service with a UI rather than an embedded library
