I have only around 6 columns - from a total of more than 30 I would use. The initial data set contains 54 MB data with 1.5lakh lines. I am unable to update the data set - even with the bare minimum columns I need.
I uploaded my file of 7.5MB first .. and then when I updated the dataset with my 2nd file - all contents of the first one is lost?
My total overall - all inclusive file size is 54MB
stripped down to teh columns I need - the file size is 20MB.
