> I used the following to measure `IntegrationJsonWriter::WriteRecordBatch()
+ Finish()` on a 1M-row `RecordBatch`:
Thanks. I also tried it.
simdjson: 69 ms
RapidJSON: 65 ms
Is RapidJSON fast enough? Is simdjson not fast?
Can we try naive `std::ostringstream` implementation something like the
following?
```cpp
namespace arrow::json {
class ARROW_EXPORT JsonWriter {
// ...
private:
// ...
std::ostringstream output_;
// ...
};
}
namespace arrow::json {
void JsonWriter::StartObject() {
MaybeComma();
output_ << "{";
needs_comma_ = false;
}
// ...
```
If this performance is similar to simdjson/RapidJSON, they may not be so
fast for writing.
If this is slower than simdjson/RapidJSON, both of them are fast.
