## What it is
LTS (light-task-scheduler) is a Java distributed scheduled job framework supporting real-time, scheduled, and Cron tasks with horizontally scalable, stateless nodes. It includes JobClient, JobTracker, TaskTracker, and an LTS-Admin console, using Zookeeper/Redis for registry and Mongo/MySQL for task queues.

## Use cases
- run distributed cron jobs across a cluster
- schedule one-off tasks at a specific time
- execute real-time tasks with load balancing
- monitor and manage scheduled jobs from an admin console
- add fault-tolerant task submission with FailStore
- dynamically add or modify job parameters at runtime

## When to choose
- you need a Java distributed job scheduler with Spring integration
- you want scalable, stateless task execution nodes with master election
- you need an admin UI for job queue and node monitoring

## When to avoid
- you need a single-node cron scheduler like Quartz only
- your stack is not JVM-based
- you need a project with frequent recent releases

## Facets
- artifact type: framework
- maturity: maintenance
- function: scheduling, workflow-automation, message-queue, monitoring
- domain: microservices, backend
- platform: jvm, cross-platform, self-hosted
- tags: distributed-task-scheduling, cron-jobs, job-scheduler, spring-integration, zookeeper, failover, job-tracker, task-tracker, automation, devops
