I wonder if the latency can be reduces by calling `flush()` on the underlying Decoder when the driver program knows (somehow) that it has received the end of a record and is not in the middle of decoding. https://docs.rs/arrow-csv/32.0.0/arrow_csv/reader/struct.Decoder.html#method.flush Perhaps something like ```rust let mut next = move || { loop { // force flush to produce RecordBatches if we have fed the entire input // that is available and are sure the data has only complete rows let decoded = if check_have_read_to_boundary() { decoder.flush() decoder.decode(buf) } else { let buf = reader.fill_buf()?; decoder.decode(buf); }?; if decoded == 0 { break; } reader.consume(decoded); } decoder.flush() }; ``` -- This is an automated message from the Apache Git Service.
