There are STRINGLAST/LONGLAST or LATEST functions for native <https://druid.apache.org/docs/latest/querying/aggregations.html> or SQL <https://druid.apache.org/docs/latest/querying/sql.html> queries, for basic string or number fields. However, if there are cumulative metrics, they can't use these, so you'd need to be cautious about the new rows and what data they contain.
