I had applied sampling on a non unique multi-column primary key with high cardinality ( but thousands of rows per key value) on a large fact
table, as well as on some of the low cardinality columns.
The multi-column key consisted of date (new rows always fall outside the domain), chain (static number of chains), and SKU (fairly static set
of values).
