Wes McKinney commented on ARROW-6820:
-------------------------------------
I think we should have suggested names, but requiring certain names seems
fraught. Since Map data might come from external sources (Spark, Parquet), I
don't think it would be appropriate to overwrite the field names that might be
used already in those sources.
> [C++] [Doc] [Format] Map specification and implementation inconsistent

> Key: ARROW-6820
> URL: https://issues.apache.org/jira/browse/ARROW-6820
> Project: Apache Arrow
> Issue Type: Bug
> Components: C++, Documentation, Format
> Reporter: Antoine Pitrou
> Priority: Blocker
> Fix For: 1.0.0
>
>
> 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).
