+#### Group does not guarantee sort order
+`group()` does not guarantee the sort order of output records.
+To ensure data is sorted correctly, use [`sort()`](/v2.0/reference/flux/stdlib/built-in/transformations/sort/)
+after `group()`.
+
+```js
+data
+  |> group()
+  |> sort(columns: ["_time"])
+```
