Whose result can be trusted is beside the point - I actually believe both experiments were likely conducted in good faith but with incomplete context. But that’s beside the point. The point is there’s no good reason to start a benchmark war to begin with.

> While performing the benchmarks, we noticed that the Snowflake pre-baked TPC-DS dataset had been recreated two days after our benchmark results were announced. An important part of the official benchmark is to verify the creation of the dataset. So, instead of using Snowflake’s pre-baked dataset, we uploaded an official TPC-DS dataset and used identical schema as Snowflake uses on its pre-baked dataset (including the same clustering column sets), on identical cluster size (4XL). We then ran and timed the POWER test three times. The first cold run took 10,085 secs, and the fastest of the three runs took 7,276 seconds. *Just to recap, we loaded the official TPC-DS dataset into Snowflake, timed how long it takes to run the power test, and it took 1.9x longer (best of 3) than what Snowflake reported in their blog.* https://databricks.com/blog/2021/11/15/snowflake-claims-simi...
