Trying out the new preview feature for data qquality by column. Counts and distribution seems to be reasonable, but column quality shows the same for all columns.
I would think that this wpould be interpretted as 97% of the value are valid for the data type selected, and 2% are in error.
Also, I have a an append query for two Excel file data sources, with 46 columns, saves it's profiling top 1000 rows, but it takes surprisingly long to generate, let it run for over 2 minutes and did not come back, still spinning.
Please advise on the column data quality metrics.
Thanks
