Class SSESourceFunction<T>

java.lang.Object

org.wikimedia.eventutilities.flink.stream.SSESourceFunction<T>

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.functions.Function, org.apache.flink.api.java.typeutils.ResultTypeQueryable<T>, org.apache.flink.streaming.api.functions.source.SourceFunction<T>

public class SSESourceFunction<T>
extends Object
implements org.apache.flink.streaming.api.functions.source.SourceFunction<T>, org.apache.flink.api.java.typeutils.ResultTypeQueryable<T>

Server Sent Events (AKA EventSource) Flink SourceFunction. Reads SSE from the HTTP URI and deserializes the events using the provided DeserializationSchema NOTE: This should not be used for 'production' jobs. It uses the deprecated SourceFunction, and has not been thoroughly tested. This is mostly useful for development and testing. Usage: SSESourceFunction source = new SSESourceFunction(endpoint, new SimpleStringSchema()); datastream = env.add_source(source); datastream.print();
