There is a PR from me (Daniël, committer) with for db-benchmark. For the group by benchmarks, on my machine, it is currently somewhat slower than the fastest (Polars).

https://github.com/h2oai/db-benchmark/pull/182

Also we do support running TPC-H benchmarks. For the queries we can run, those are already finishing faster than Spark. We are planning to do more benchmarking and optimizations in the future.

That's really promising, considering how fast Polars is. Both are written in Rust and use Apache Arrow, so they can even co-exist in the same context.

Yes, that's pretty exciting! There is even support in Polars to execute the dataframe compute in DataFusion (as it can handle larger than memory datasets).
