Kafka useful administration tool


This is a rack-aware tool for assigning Kafka partitions to brokers that minimizes data movement. It also includes the ability to inspect the current live brokers in the cluster and the current partition assignment.

Using this tool will greatly simplify operations like decommissioning a broker, adding a new broker, or replacing a broker.

Kafka Tools

This repository is a collection of tools for working with Apache Kafka.
The Site Reliability team for Kafka at LinkedIn has built these over time in order to make managing Kafka a little bit easier. Our intention is to add to this repository as more tools are developed.
We welcome additions and modifications that make managing Kafka better for all!
