Add bonus difficulty to `split-descriptive-statistics` for big datasets
hopefully will fix ` JobManagerExceededMaximumDurationError` for `split-descriptive-statistics` for big datasets like https://huggingface.co/datasets/Open-Orca/OpenOrca. It appears that loading data to in-memory table takes too much time

We can try like this and meanwhile I'm exploring other options how to query faster on big data
