### Describe the enhancement requested Manipulating field and schema metadata in the JS bindings currently requires manually constructing Map<string, string> instances and re-instantiating Field/Objects objects. Other Arrow implementations: - C++ [Field](https://github.com/apache/arrow/blob/main/cpp/src/arrow/type.cc#L308-L311) + [Schema](https://github.com/apache/arrow/blob/main/cpp/src/arrow/type.cc#L2465-L2468) - Rust [Field](https://docs.rs/arrow-schema/57.0.0/src/arrow_schema/field.rs.html#366-369) + [Schema](https://docs.rs/arrow-schema/57.0.0/src/arrow_schema/schema.rs.html#244-246)) expose a helper that replaces a field/schema’s metadata map (and accepts null/None to clear it). **Request** Add a `Field.withMetadata()`, and `Schema.withMetadata()` method that: - Accepts a `Map<string, string>`, a plain object `Record<string, string>`, or `null` (to clear metadata). - Returns a new Field with the supplied metadata (replacement semantics, not merging). This brings the JavaScript bindings in line with the existing C++/PyArrow/Rust APIs and makes metadata updates more ergonomic (and less error-prone). -- This is an automated message from the Apache Git Service.
