Batch Mode – part 3 (“Basic Heuristics and Analysis”)

Read Original

This technical article, part of a series on Batch Mode, analyzes the heuristics SQL Server's Query Optimizer uses to enable Batch Mode execution. It discusses conditions like analytic operators, aggregations, and row counts, while cautioning that Microsoft's internal logic may change. The post introduces the `batch_mode_heuristics` Extended Event for deeper analysis and ties the concepts to Columnstore Indexes.
