Dylan1312 commented on issue #7187: Improve topN algorithm URL: https://github.com/apache/incubator-druid/issues/7187#issuecomment-469658363 Also curious on people's thoughts on user's being explicit in their queries that can return approximate results versus optimising queries based on context/configuration. `SELECT AGG(y), x FROM tbl where x in (SELECT FREQ_I_SKETCH(x, y, 100) from tbl) ` versus trying to optimise a order by limit.
