Flink stateful functions
WebFor every message, this function will calculate its new count, send a message to the printer function we made earlier, then update its state with the new count. Internally this is batched over many events before sending state back to Flink for efficiency. NOTE: For JSON (or anything other than protobuf) messages, you must use sendByteMsg instead. WebDeployment and Operations # Stateful Functions runtime, which manages state and messaging for an application, is built on top of Apache Flink, which means it inherits Flink’s deployment and operations model. Read through the official Apache Flink documentation to learn how to run and maintain an application in production. The following pages outline …

WebApache Flink Documentation # Apache Flink is a framework and distributed processing engine for stateful computations over unbounded and bounded data streams. Flink has been designed to run in all common cluster environments, perform computations at in-memory speed and at any scale. Try Flink # If you’re interested in playing around with … WebStateful Functions is an API that simplifies building distributed stateful applications. It’s based on functions with persistent state that can interact dynamically with strong consistency guarantees. A Stateful Functions application is basically just an Apache Flink Application and hence can be deployed to Kinesis Data Analytics.
