Multiple Join Size Estimation by Virtual Domains (extended abstract)

Summary: Introduces "virtual domains" to estimate sizes of intermediate relations for complex multi-equijoin expressions, avoiding the unrealistic underestimates caused by attribute-independence assumptions while requiring little database statistics. Presents an exact model plus a lightweight, fast approximation tailored for optimizer search over many alternative plans. (summarized by gpt-5-mini on Feb 09 2026)
