Wes McKinney created ARROW-3151:
-----------------------------------
Summary: [C++] Create Protocol Buffers interface for iterating
over the semantic "rows" of a record batch, and accessing the rows using the
protobuf API
Key: ARROW-3151
URL: https://issues.apache.org/jira/browse/ARROW-3151
Project: Apache Arrow
Issue Type: New Feature
Components: C++
Reporter: Wes McKinney
The desired workflow:
* User writes a .proto file describing the structure of a "row" as a Message
* Given the generated pb.h bindings, an Arrow users can iterate over an
{{arrow::RecordBatch}}, each iteration populating an instance of the Row message
* The values of the row can then be accessed via the standard Protobuf APIs
A corresponding interface could be developed to write a RecordBatch using
protobufs as input, but that could be its own project
