Confluent is hosting a Kafka Summit Hackathon on May 7th in New York City, where developers can learn how to build streaming applications with Apache Kafka. The hackathon aims to demonstrate the power of microservices combined with stream processing, using the Kafka Streams API or other Kafka clients for programming languages such as Java, C/C++, Python, and Go. Participants will have access to a vibrant ecosystem and community that provide application developers with Kafka clients for various programming languages. A panel of judges will select the most outstanding project based on creativity, features, and completeness, with prizes awarded to open-sourced code. The event is free and open to anyone, including Kafka Summit attendees.
