Micah Kornfield commented on ARROW-6820: ---------------------------------------- /// The names of the /// child fields *may* be respectively "entry", "key", and "value", *but this is* */// not enforced* I'm not sure I understand the issue. The way I read the spec, naming is not enforced. See bolded section. > [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). -- This message was sent by Atlassian Jira (v8.3.4#803005)
