The #stream() method works in the same way as #eachRow() but instead of callback it returns a Readable Streams2 object in objectMode that emits instances of Row.
The #stream() method works in the same way as #eachRow() but instead of callback it returns a Readable Streams2 object in objectMode that emits instances of Row. It can be piped downstream and provides automatic pause/resume logic (it buffers when not read).
