gianm commented on issue #9321: Performance degradation in topN queries when SQL-compatible null handling is enabled URL: https://github.com/apache/druid/issues/9321#issuecomment-591672502 Btw, have you tried the vectorized groupBy engine? It doesn't apply in every case yet (see the docs at https://druid.apache.org/docs/latest/querying/query-context.html#vectorizable-queries) but I'm curious how well it works for you. We'd like to make this the default in a future release.
