Gian Merlino dbed1b0f50 Defer more expressions in vectorized groupBy. (#16338) ... * Defer more expressions in vectorized groupBy. This patch adds a way for columns to provide GroupByVectorColumnSelectors, which controls how the groupBy engine operates on them. This mechanism is used by ExpressionVirtualColumn to provide an ExpressionDeferredGroupByVectorColumnSelector that uses the inputs of an expression as the grouping key. The actual expression evaluation is deferred until the grouped ResultRow is created. A new context parameter "deferExpressionDimensions" allows users to control when this deferred selector is used. The default is "fixedWidthNonNumeric", which is a behavioral change from the prior behavior. Users can get the prior behavior by setting this to "singleString". * Fix style. * Add deferExpressionDimensions to SqlExpressionBenchmark. * Fix style. * Fix inspections. * Add more testing. * Use valueOrDefault. * Compute exprKeyBytes a bit lighter-weight.		2024-06-26 17:28:36 -07:00
