WebDec 2, 2024 · Flink's built-in latency metrics measure the time it takes for latency tracking markers to travel from the sources to each downstream operator instance. These markers travel with your stream records, waiting their turn in network queues, but skip over your user functions. This means that the actual latency will be larger. WebFlink is a stream processing framework that can run the chores requiring batch processing, giving you the option to use the same algorithm in both the modes, without having to turn to a technology like Apache Storm that requires low latency response.
