"Many teams are now using schemas and schema registries to bring structure to their Kafka records, but how do you get clients connected in a consistent way? AsyncAPI is an open source initiative that makes working with event-driven architectures as easy as working with REST APIs. From API documentation to code generation, and from discovery to event management, this open source initiative provides a language and tooling to describe your asynchronous APIs. This talk will be an introduction to help developers get started with using AsyncAPI. It will cover how to describe your Kafka cluster and define how clients should connect. Come along to learn about how AsyncAPI complements and extends existing use of schema formats like Apache Avro and why you should start using it today as part of your event-driven architecture."

How can I start using these topics
as efficiently as possible?
When I find topics I want to use, how can
I understand the data that is on them?
How can I know what Kafka clusters and topics
are available for me to use in my company?
???
