Trino implemented a variant of TopNRowNumber node + operator called TopNRanking - which improves Q67 performance signficantly. In my local testing with TPCDS SF 1000, I saw a performance improvement in latency of around 80%

This looks like a good candidate to add to Presto as well, both in Presto Java & Native
