The academic paper tests four obscure, non-production databases on an irrelevant benchmark (TPC-H) to provide far-fetched claims.

It looks like PHP is ideal.

Adding Merge Tree compaction, a la ClickHouse, should solve this, right?

I was surprised to see such a big jump in ClickHouse (up 7 places). Now it's higher than Spark but lower than Hive and HBase (they were trendy around the first half of 2010x).

But the demo does not work.

I tried "England is" and a few similar queries. It spends three seconds then shows that nothing is found.
