For druid if there are more than 5 measures in the toplist or if toplist returns results equal to the limit rows then we do a second query by adding those top values as a filter. It has been observed in past for kargo and now for automatad as well that if we remove the limit clause from this query then this is run as a groupby query (instead of topN) and it is much faster than topN. More details in an internal notion doc.
