Definition - What does Cardinality mean? In the context of databases, cardinality refers to the uniqueness of data values contained in a column. High cardinality means that the column contains a large percentage of totally unique values. Low cardinality means that the column contains a lot of ârepeatsâ in its data range.
If the cardinality of a table is way bigger than cardinality of a column, using that column for index will not be so efficient, so you have to add some more columns to the index whose cardinality is big enough, you may even drop that column from the index.
