Database Index Density Vectors

This collection provides a list of density values for each combination of columns in a specific database index.

Type

SQL Server.

Collection Sampling Intervals

This collection is an on-demand collection, which has no pre-defined sampling intervals.

Display Name
Description

All Density

Density is the term used by SQL Server to represent the selectivity of the index columns. The more selective an index is, the more useful it is in searches.

Calculated as 1 / distinct values for all values in the first key column of the statistics object, excluding the histogram boundary values. This Density value is not used by the query optimizer, and is displayed for backward compatibility with versions prior to SQL Server 2008.

Avg Key Length

Average number of bytes per value for all of the key columns in the statistics object.

Columns

The names of the columns in the index.

Database Index Details

This collection provides general statistics about a specific database index.
