Session 11: Spool operator in SQL Server

This session covers spool operators in SQL Server, focusing on their functions and impact on query performance. It explains the physical operator functions (Init(), GetRow(), GetNext(), Close()) and the concepts of rebinds and rewinds, which are relevant when the Nested Loops operator interacts with certain operators like Index Spool and Table Spool. The presentation also discusses different types of spools (Table Spool, Index Spool, Row Count Spool, Windows Spool) and their use cases, such as ensuring the availability of the original table copy for insert, update, and delete operations, and making the same copy of data available for multiple branches of the execution plan.
