## What it is
Kala is a simplistic, modern job scheduler written in Go that runs as a single binary with a JSON-over-HTTP API and a web UI. It supports ISO 8601 and interval scheduling, retries, dependent jobs, and persistence via multiple database backends like BoltDB, Redis, Postgres, and Mongo.

## Use cases
- schedule recurring jobs with cron-like ISO 8601 intervals
- run background tasks from a simple HTTP API
- replace Chronos with a simpler job scheduler for a startup
- chain dependent jobs with retries
- persist scheduled jobs in Redis, Postgres, Mongo, or BoltDB
- manage scheduled jobs through a web dashboard

## When to avoid
- you need battle-tested fault tolerance or massive scale
- you need distributed scheduling across a cluster
- you need complex workflow orchestration features

## Facets
