Documentation
Definition
High Cardinality means that this dimension contains a high number of attributes. This information is used to execute physical optimizations, depending on the database platform. For example, different index types from those in a standard case are used. Generally, a dimension has a high cardinality if the number of dimension entries is 20% (or more) of the number of fact table entries. When in doubt, do not set a dimension with high cardinality.
