## What it is
A Kubernetes operator for Apache Flink, implemented in Java, that manages the full lifecycle of Flink Application, Session, and Job deployments through native Kubernetes tooling. It provides deployment, upgrade, suspend/delete operations, logging and metrics integration, and a built-in Flink Job Autoscaler.

## Use cases
- deploy and manage Apache Flink jobs on Kubernetes with kubectl
- automate lifecycle management of Flink deployments including upgrades and suspension
- autoscale Flink jobs based on load
- run Flink session clusters on Kubernetes
- monitor Flink applications with integrated logging and metrics
- manage Flink deployments declaratively via Kubernetes CRDs

## When to choose
- you run Apache Flink workloads on Kubernetes and want native k8s lifecycle management
- you need automated deployment, upgrade, and rollback of Flink jobs
- you want autoscaling for Flink jobs without manual resource tuning
- you prefer managing streaming jobs declaratively with kubectl and CRDs

## When to avoid
- you don't use Kubernetes as your deployment platform
- you run Flink on standalone clusters, YARN, or other resource managers
- you need a general-purpose stream processing engine rather than a deployment operator
