> Maybe adding an `IS NOT false` to the left_col = right_col predicate here, if `right_col` is nullable, would fix this: > I completely agree with your @msirek idea. Currently, in datafusion, by adding `IS NOT FALSE` to the `in_predicate`, can transform an equijoin into a non-equijoin, thereby using NestedLoopJoinExec to execute and resolve the issue. In future development, when anti-join uncorrelated subqueries support the hash join algorithm, it would enable optimizing broadcast null. @alamb, what are your thoughts on this? -- This is an automated message from the Apache Git Service.
