@thinkharderdev @liurenjie1024 I think the 'Bubble Execution' model is what exactly you would like to achieve. And as I know, Alibaba's MaxCompute engine had already implemented the 'Bubble Execution' model. https://alibaba-cloud.medium.com/dag-2-0-the-adaptive-execution-engine-that-supported-150-million-distributed-jobs-in-the-2020-31ffad8bd722 Some questions are still not clear to me as of now, particularly if we plan to bring pipeline based scheduling( (Morsel-Driven Parallelism) into Ballista, then what's the relationship between Bubble, Stage and Pipeline, and how to divide the DAG into Bubbles, how to split the Stage into multiple Pipelines etc. -- This is an automated message from the Apache Git Service.
