Process the transpose by making multiple passes over the dataset. Useful for really big datasets. Consumes memory relative to the number of rows. Note that in general it is faster to process the transpose in memory.

The field delimiter for reading CSV data. Must be a single character. (placeholder: ,)

Check if there is enough memory to load the entire CSV into memory using CONSERVATIVE heuristics. This option is ignored when computing default, streaming statistics, as it is not needed.
