> We currently use maxPartitionBytes and minPartitionNum to split files and use 
> openCostInBytes to merge file splits. But these are static configurations, 
> and the same configuration does not work in all scenarios.
> This PR attempts to dynamically merge file splits, taking into the 
> concurrency while processing more data in one task.
