Datasetq: jq for Datasets; Polars-powered Parquet/JSON/CSV query lang/cli

Whenever I see things like this I always wonder how they compare with other cli tools. In the context of this tool, built in rust with polars integrated, I'm wondering how this compares with nushell. But are written in rust and have access to polars.

no doubt, jq language makes sense for hierarchical data structures but how much useful is it for table formats? ie duckdb can do all of that
