PR Code Suggestions ✨

Explore these optional code suggestions:

Category	Suggestion	Impact
Possible issue	Handle null values in boolean comparisons Consider the semantic correctness of these boolean comparison operators. In SQL, IS NOT TRUE evaluates to true for both false and null values, while IS NOT FALSE evaluates to true for both true and null values. Ensure the implementation handles null values correctly according to SQL three-valued logic. sandbox/libs/analytics-framework/src/main/java/org/opensearch/analytics/spi/ScalarFunction.java [41-44] IS_TRUE(Category.COMPARISON, SqlKind.IS_TRUE), IS_FALSE(Category.COMPARISON, SqlKind.IS_FALSE), -IS_NOT_TRUE(Category.COMPARISON, SqlKind.IS_NOT_TRUE), -IS_NOT_FALSE(Category.COMPARISON, SqlKind.IS_NOT_FALSE), +IS_NOT_TRUE(Category.COMPARISON, SqlKind.IS_NOT_TRUE), // Returns true for FALSE and NULL +IS_NOT_FALSE(Category.COMPARISON, SqlKind.IS_NOT_FALSE), // Returns true for TRUE and NULL Suggestion importance[1-10]: 7 __ Why: The suggestion correctly identifies the semantic behavior of IS_NOT_TRUE and IS_NOT_FALSE in SQL three-valued logic. However, it only asks to verify/ensure correct handling through comments rather than proposing actual implementation changes, limiting its immediate impact.	Medium
