Q: Partitioning by date is common. Where should the dates go in the folder hierarchy?
Almost always, you will want the dates to be at the end of the folder path. This is because we often need to set security at specific folder levels (such as by subject area), but we rarely set up security based on time elements.
Optimal for folder security: \SubjectArea\DataSource\YYYY\MM\DD\FileData_YYYY_MM_DD.csv
Tedious for folder security: \YYYY\MM\DD\SubjectArea\DataSource\FileData_YYYY_MM_DD.csv
