• [X] I have searched in the issues and found no similar issues.

What would you like to be improved?

The Mixed Format KeyedTable splits tasks based on nodes (hash). If the number of split tasks is insufficient, it will lead to inadequate concurrent utilization by the optimizer, resulting in a longer process execution time.

How should we improve?

We should use bin-packing to split the files in one node into several tasks when it's necessary.
