### What problem does this PR solve? Lance regular scans currently leave common string predicates and direct boolean predicates in Doris, so Lance cannot filter rows before Arrow materialization and transfer. ### What is changed? - Push two-argument `LIKE` / `NOT LIKE` predicates without backslash escapes through the existing Substrait filter. - Push `starts_with(column, literal)` and `ends_with(column, literal)`. - Push direct boolean-column predicates, including `NOT boolean_column`. - Keep explicit/custom LIKE escapes, REGEXP, non-literal patterns, and non-string inputs as Doris residual predicates. - Extend FE unit and external Lance regression coverage. ### Testing - `mvn -pl fe-core -am -Dtest=LancePredicateConverterTest -DfailIfNoTests=false test` (21 passed) - `test_lance_scalar_predicate_pushdown` against local MinIO + FE + BE - Manual end-to-end LargeUtf8 `starts_with` verification ### Release note Improve Lance predicate pushdown for common string and boolean expressions. -- This is an automated message from the Apache Git Service.
