Instead of reading from a continuous stream, it reads a bounded dataset off of persistent storage as a stream. Flink uses the exact same runtime for both of these processing models. Flink offers some optimizations for batch workloads.
WebApache Flink supports both streaming and batch and undertakes real-time data collection, real-time calculation, and downstream transmission in high-demand scenarios. WebOct 15, 2024 · Flink streaming jobs with finite sources shut themselves down once the input has been exhausted. One final watermark with the value MAX_WATERMARK gets sent through the pipeline, which triggers all event time windows, but processing time windows are only fired if they are still running when the appointed time arrives.
