WebIteration # Iteration is a basic building block for a ML library. In machine learning algorithms, iteration might be used in offline or online training process. In general, two types of iterations are required and Flink ML supports both of them in order to provide the infrastructure for a variety of algorithms. Bounded Iteration: Usually used in the offline … WebJun 14, 2024 · Flink: iterations are executed as cyclic data flows; a program (with all its operators) is scheduled just once and the data is fed back from the tail of an iteration to its head. This allows Flink to keep all additional data locally. Spark: each iteration is a new set of tasks scheduled and executed.
