### Rationale for this change Arrow currently supports JSON reading in C++, but it currently lacks an equivalent JSON writer. This means users are suffer marshalling overhead when writing JSON through languages such as Python. ### What changes are included in this PR? This implements a writer for line-delimited JSON, and the API is based on the CSV writer. It is implemented using the `RowBatchBuilder` from the `cpp/examples/arrow/rapidjson_row_converter.cc` example, with some improvements: 1. Date and time types are supported and written as numbers. 2. Optionally emits nulls. There are no bindings for other languages implemented yet. ### Are these changes tested? Yes, with C++ unit tests. There are also a few benchmarks based on the CSV writer benchmarks. ### Are there any user-facing changes? Yes, a new JSON writer API. -- This is an automated message from the Apache Git Service.
