each network shuffle, takes time and adds to latency. 5. If the application emits through a transactional sink, the sink will only commit and publish transactions upon successful checkpoints of Flink consider latency, which is introduced inside the Flink topology and cannot be attributed to transactional sinks or events being buffered for functional reasons (4.). To this end, Flink comes with a feature
