Implement reading of number of rows (nrows) in read_csv by using spark's limit.
On the first read, this does not seem to help much with regards to reading speed, because
inferSchema
is True and spark seems to scan over the full data anyway (see e.g. here). It would help to use it as a similar parameter toread_csv
than in pandas to make the API more compatible.
