Kafka Confluent Platform

About Confluent

Confluent is a company founded by the team that built Apache Kafka. It builds a platform around Kafka that enables companies to easily access data as real-time streams.

Confluent offers three different ways to get started with Kafka.

  1. Confluent Open Source
  2. Confluent Enterprise
  3. Confluent Cloud

While we in this series of Kafka Tutorial discuss much about Confluent Open Source, you may check the other two ways based on your requirement and interest.

While comparing Confluent Open Source with Apache Kafka, we get the following capabilities or tools in addition to standard Apache Kafka :

  • Additional Clients : Supports C, C++, Python, .NET and several other non-Java Clients.
  • REST Proxy – Provides universal access to Kafka from any network connected device via HTTP
  • Schema Registry – Central registry for the format of Kafka data – guarantees all data is always consumable
  • Pre-Built Connectors – HDFS, JDBC, Elasticsearch, Amazon S3 and other connectors fully certified and supported by Confluent
