Very interesting development :)

DataFusion committee here.

DuckDB can work on Arrow data, so I think it could coexist with DataFusion / Ballista quite well. I am not sure whether having different execution engines for Ballista is on the roadmap, but it's certainly a possibility!

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).

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).

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.

Happy for this release, and excited to contribute to this great query engine.
