DuckDB, Daft, Polars and DataFusion are compared by concrete outcomes: a workload shows 2× performance boost in under a year, a 150 GB CSV processes on a single node with 2 cores and 16 GB RAM, and open table formats let local Python engines read cloud-style tables. Cache behavior to remote storage becomes the real bottleneck, some engines stream and spill to disk while others need more cores, and SQL interoperability often wins over proprietary Python APIs.
