+// This files contains some utilities to convert Doris internal
+// data format into/from Apache Arrow format. When Doris needs
+// to share data with others we can leverage Arrow's ability.
+// We can convert our internal data into Arrow's memory format
+// and then convert to other format, for example Parquet. Because
+// Arrow have already implemented this functions. And what's more
+// Arrow support multiple laguages, so it will make it easy to
+// handle Doris data in other laguages.
