Two recent posts on the Percona blog caught my attention. In Replicating from InnoDB into a DuckDB storage engine and The DuckDB MySQL engine at 500 GB, Evgeniy Patlan wired DuckDB into mysqld as a storage engine, pointed row-based replication at it, and measured it at TPC-H scale factor 500. The numbers are striking: loads 25 times faster than InnoDB, one fifth of the disk, and the full 22-query TPC-H suite done in 186 seconds where InnoDB needed about 28 hours and never finished four of the queries.
