In this blog post we’ll define cardinality and high cardinality, and explore the role of cardinality in monitoring and observability.
Cardinality’s official, non-database dictionary definition is mathematical: the number of values in a set. When applied to databases, the meaning is a bit different: it’sthe number of distinct values in a table column relative to the number of rows in the table. Repeated values in the ...
