High Cardinality

The High Cardinality property allows you to create more than two thousand million characteristic attributes for a characteristic.

As a characteristic with high cardinality has a number of restrictions, you should only set this property if you really expect a larger number of characteristic attributes.A characteristic with high cardinality has no persistent SID values and no SID table. This kind of characteristic can therefore only be used in InfoProviders that store the key instead of the SID value of the characteristics it contains.
