+Load the sample dataset using INSERT and EXTERN functions. The EXTERN function
lets you read external data or write to an external location.
Review Comment:
Give that the example uses both [INSERT
INTO](https://druid.apache.org/docs/latest/multi-stage-query/reference/#insert)
and
[EXTERN](https://druid.apache.org/docs/latest/multi-stage-query/reference/#extern-function),
at the very least we should link to the relevant docs.
For example:
Load the same dataset using the INSERT INTO statement and the EXTERN
function.
