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. WebStateful Functions is based on iteration and arbitrary message passing. Because records can go in any direction through the dataflow, event time is not well defined.

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.

WebFor fault-tolerant state, the ProcessFunction gives access to Flink’s keyed state, accessible via the RuntimeContext, similar to the way other stateful functions can access keyed state. The timers allow applications to react to changes in processing time and in event time.

WebApr 6, 2024 · E.g., a QA tool that verifies that our StateFun persisted state is consistent with the data in our transactional database. Ideally we would be able to do this in a standalone program, but being able to do this in a Flink job would be workable. Our functions are implemented in Node.js, but I assume I'll need to use Java to view persisted state.
