Project description

Kafka Connect Python

The Kafka Connect REST API allows you to manage connectors that move data between Apache Kafka and other systems.

The Kafka Connect command line tool, also known as kc or kafka-connect, allows users to manage their Kafka Connect cluster and connectors. With this tool, users can retrieve information about the cluster and connectors, create new connectors, update existing connectors, delete connectors, and perform other actions.

This project aims to supported all features of the Kafka Connect REST API.
