## What it is
Azkaban is an open-source batch workflow job scheduler created at LinkedIn to run Hadoop and data warehouse jobs. It resolves job execution ordering via dependencies and provides a web UI for uploading, scheduling, and tracking workflows.

## Use cases
- schedule hadoop batch jobs with dependencies
- orchestrate etl workflows with a web ui
- retry failed jobs and get email alerts on failure
- sla alerting and auto-killing for long-running workflows
- manage and upload workflow projects via web or http
- run data warehouse pipelines on a schedule

## When to choose
- you run hadoop or big-data batch pipelines and need dependency-based scheduling
- you want a self-hosted workflow manager with a simple web UI and pluginable auth
- you need SLA alerting, retries, and email notifications for batch jobs

## When to avoid
- you need a modern actively-evolving orchestrator like Airflow for cloud-native stacks
- your workloads are streaming or event-driven rather than batch
- you need Kubernetes-native or Python-based workflow orchestration

## Facets
- artifact type: service
- maturity: maintenance
- function: workflow-automation, scheduling, web-framework, auth, monitoring, alerting
- domain: big-data, self-hosted, developer-tools
- platform: jvm, self-hosted
- tags: workflow-manager, job-scheduler, hadoop, batch-processing, etl-orchestration, web-ui, data-engineering, automation, linux, macos, web-server
