Analyzing the Impact of Cardinality Estimation on Execution Plans in Microsoft SQL Server
Summary: Empirical study of cardinality-estimation effects on plan quality in Microsoft SQL Server using complex real-world queries (aggregates, outer joins, subqueries) and both row- and column-oriented layouts. Introduces a sensitivity analysis that selectively supplies accurate subexpression cardinalities while injecting graded errors, and evaluates runtime mitigations (bitmap filtering, adaptive joins).
