      Description

      In https://arrow.apache.org/docs/format/Layout.html#map-type, the map type is specified as having a child field "pairs", itself with children "keys" and "items".

      In https://github.com/apache/arrow/blob/master/format/Schema.fbs#L60, the map type is specified as having a child field "entry", itself with children "key" and "value".

      In the C++ implementation, a map type has a child field "entries", itself with children "key" and "value".

      In the Java implementation, a map vector also has a child field "entries", itself with children "key" and "value" (by default).
