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.

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. WebThe closure cleaner removes unneeded references to the surrounding class of anonymous functions inside Flink programs. With the closure cleaner disabled, it might happen that an anonymous user function is referencing the surrounding class, which is usually not Serializable. This will lead to exceptions by the serializer.
