Apache Kafka® is a powerful open-source distributed event streaming platform, but it lacks an opinion about the structure of data. To address this issue, Karapace provides an open source HTTP API interface and schema registry for Apache Kafka®. Key features include a schema registry that allows producers to validate their payload against expected schemas before producing records on topics, and RESTful API endpoints for Apache Kafka, which enable working directly with data and metadata over HTTP. Karapace is an open source Python-based project released under the Apache 2.0 license, making it easy for developers to contribute and enhance its functionality.
