## What it is
kube-batch is a batch scheduler for Kubernetes designed for high-performance workloads such as AI/ML, Big Data, and HPC jobs. It was the predecessor to the Volcano project and has since been retired/archived.

## Use cases
- schedule batch jobs on kubernetes
- gang scheduling for distributed ML training
- run HPC workloads on kubernetes
- schedule big data jobs like Spark on k8s
- co-schedule pods as a group for AI workloads

## When to choose
- you are on a very old Kubernetes cluster without Volcano and need gang scheduling
- you need a lightweight standalone batch scheduler for kubernetes
- you are studying the design lineage of Volcano

## When to avoid
- starting a new project - use Volcano instead, which is its actively maintained successor
- you need support, bug fixes, or compatibility with recent Kubernetes versions
- you need general-purpose pod scheduling rather than batch/gang scheduling
