We’re excited to announce the launch of Karapace, a replacement for Apache Kafka REST and the Schema Registry.
An open-source alternative to Schema Registry and Apache Kafka REST proxy
Karapace is a fully open source tool developed by Aiven. Karapace’s functionality aims to be 1:1 compatible with the existing Confluent Schema Registry and the Apache Kafka REST proxy, and it works on both client and server sides.
On the technical side, Karapace represents moderate memory consumption and is built with an asynchronous architecture. This makes Karapace a lightweight and stable tool, and working with Apache Kafka gets just a little easier.
As an open-source replacement for proprietary solutions, Karapace helps you to avoid vendor lock-in.
Karapace currently provides the following functionality:
- A central repository for storing schemas
- Serialization and deserialization of messages
- Version history of Kafka schemas
- A RESTful interface for your Kafka cluster
Karapace can also produce and consume messages and handle cluster administration tasks.
Getting started with Karapace
To enable Schema Registry or REST proxy for your Aiven for Kafka plans, go to the Overview page of your Aiven for Apache Kafka service, and enable the features.
