WebJan 4, 2024 · When scheduling tasks, Flink needs to iterate over all the connections between result partitions and consumer vertices. In the past, since there were O (n 2) edges in total, the overall complexity of the iteration was O (n 2 ). Now ExecutionEdge is replaced with ConsumerVertexGroup and ConsumedPartitionGroup. 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. east riding of yorkshire jobs
