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.

WebRegisters an Aggregator for the iteration. Aggregators can be used to maintain simple statistics during the iteration, such as number of elements processed. The aggregators compute global aggregates: After each iteration step, the values are globally aggregated to produce one aggregate that represents statistics across all parallel instances.
