I was trying to read S3 through Athena, in the tableau only appeared 720 occurrences, I imagine that is the amount of files. When I see the same external table through Redshift aparare the 10.127.181 records. What am I doing wrong?
Have you confirmed that you are only pulling in 720 rows? The screenshot you provided is of the preview pane, which only displays a subset of the actual data.
Try going to a sheet and dragging the Number of Records measure to the Marks card as Text to see what the true number of rows is for that data source.
Hope that helps.
