The roadmap contains both efforts in early … 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.
