> Some export formats are friendlier for streaming than others. CSV and TSV are pretty easy to stream, as is newline-delimited JSON.
> 
> Regular JSON requires a bit more thought: you can output a `[` character, then output each row in a stream with a comma suffix, then skip the comma for the last row and output a `]`. Doing that requires peeking ahead (looping two at a time) to verify that you haven't yet reached the end.
