The Cardinality Statistics panel enables TDV to collect table and column boundary statistics for a cached view (and for data sources and tables) so that the TDV query engine can use those statistics to optimize query execution plans. For details, see Updating the Query Execution Plan.

The configuration and usage of cardinality statistics is described in Creating Cardinality Statistics for Cost-Based Optimization. Refer to the topic on Creating Cardinality Statistics for a View for information on how this panel is configured and used.

Cardinality statistics are also used to optimize parallel cache loading. See Setting Up the Parallel Cache Option for more information.
