## What it is
db-scheduler is a persistent, cluster-friendly task scheduler for Java, designed as a simpler alternative to Quartz. It stores tasks in a single database table and embeds into existing applications with minimal dependencies.

## Use cases
- schedule recurring background jobs in a Java application
- run scheduled tasks across a cluster without duplicate execution
- replace Quartz with a simpler job scheduler
- persist scheduled tasks so they survive application restarts
- schedule one-off delayed tasks from a Spring Boot app
- process high volumes of scheduled executions per second

## When to choose
- you need cluster-safe scheduled jobs backed by a relational database
- you find Quartz too complex and want a minimal, embeddable scheduler
- you use Spring Boot and want easy integration
- you need high-throughput task execution with persistence

## When to avoid
- you need cron jobs outside the JVM or without a database
- you need distributed workflows with complex DAG dependencies
- your application has no relational database available
- you need a standalone scheduler service rather than an embedded library

## Facets
- artifact type: library
- maturity: stable
- function: scheduling, workflow-automation, database
- domain: backend, developer-tools, databases
