### What problem does this PR solve? Related PR: #67045, #67047 Doc: apache/doris-website#4085 Problem Summary: This PR adds MAP lambda support under the Nereids planner. Supported higher-order functions: - `map_filter((k, v) -> predicate, map)` - `map_exists((k, v) -> predicate, map)` - `map_all((k, v) -> predicate, map)` - `map_apply((k, v) -> struct(new_key, new_value), map)` - `transform_keys((k, v) -> new_key, map)` - `transform_values((k, v) -> new_value, map)` Example: ```sql SELECT map_filter( (k, v) -> v > 10, map(1, 10, 2, 20) ); SELECT transform_values( (k, v) -> v + 1, map(1, 10, 2, 20) ); SELECT map_apply( (k, v) -> (k + 1, v * 2), map(1, 10, 2, 20) ); ``` ### Implementation Use `map_entries(m)` to expand the map parameter and reuse the original `array lambda` for execution. ```text map_apply((k, v) -> (k2, v2), m) ↓ map_from_entries( array_apply(entry: struct{k, v} -> (k2, v2), map_entries(m) ); map_filter((k, v) -> k + v > 0, m) ↓ %map_from_filtered_entries_unique%( array_map( entry: strct{k, v} -> if( e.k + e.v > 0, entry, null ), map_entries(m) ) transform_values((k, v) -> k + v + col, m) ↓ %map_from_entries_unique%( array_map( entry -> (e.k, e.k + e.v + col), map_entries(m) ) ) map_exists((k, v) -> k + v = 1, m) ↓ array_match_any( array_map( entry -> e.k + e.v = 1, map_entries(m) ) ) map_all((k, v) -> k + v = 1, m) ↓ array_match_all( array_map( entry -> e.k + e.v = 1, map_entries(m) ) ) ``` ### Internal helper function This PR adds two internal Map construction functions used by the rewritten expressions: - %map_from_entries_unique%: rebuilds a Map from an entry array without running key deduplication. Used by `transform_value` - %map_from_filtered_entries_unique%: **removes** null entries input instead of throw error like `map_from_entries`. Used by `map_filter`
