### Is your feature request related to a problem or challenge? I ran some benchmarks in constrained Docker containers and found that DataFusion is pretty close to DuckDB speed when running on a single core but does not scale as well as DuckDB when more cores are added. At 16 cores, DuckDB was ~2.9x faster than DataFusion for this particular test. Cores | DuckDB 0.7.1 | DataFusion Python 21.0.0 | DuckDB x Faster -- | -- | -- | -- 1 | 315,630.9 | 318,037.8 | 1.0 2 | 155,034.5 | 197,257.3 | 1.3 4 | 75,110.0 | 111,243.1 | 1.5 8 | 37,584.9 | 73,142.3 | 1.9 16 | 18,880.3 | 55,071.8 | 2.9 ### Describe the solution you'd like I would like DataFusion to scale as well as DuckDB as more cores are added. ### Describe alternatives you've considered _No response_ ### Additional context Instructions for creating the Docker images can be found at https://github.com/sql-benchmarks/sqlbench-runners -- This is an automated message from the Apache Git Service.
