WebThis will return a BroadcastConnectedStream, on which we can call process() with a special type of CoProcessFunction. The function will contain our matching logic. The exact type of the function depends on the type of the non-broadcasted stream: ... The reason for this is that in Flink there is no cross-task communication. So, to guarantee that ... WebThe windows of Flink are used based on timers. This example shows the logic of calculating the sum of input values and generating output data every minute in windows that are based on the event time. The following sample code provides an example on how to use windows in a DataStream API to implement the logic.
WebFeb 5, 2024 · In addition to what David mentioned, if you have a keyed stream that you're connecting with the broadcast stream, then in your KeyedBroadcastProcessFunction 's processBroadcastElement () method you can iterate over all of the keyed stream state, which isn't normally something you can do in a Flink operator. WebA BroadcastConnectedStream represents the result of connecting a keyed or non-keyed stream, with a BroadcastStream with broadcast state(s).As in the case of ConnectedStreams these streams are useful for cases where operations on one stream directly affect the operations on the other stream, usually via shared state between the …
