andishgar opened a new issue, #46295: URL: https://github.com/apache/arrow/issues/46295
### Describe the enhancement requested As noted in issue #29720, The Map Layout is not described in the [specification](https://arrow.apache.org/docs/format/Columnar.html#physical-memory-layout). I’ve reopened this issue, as the previous report from four years ago appears to have been forgotten. ### Component(s) Documentation -- This is an automated message from the Apache Git Service.
