Would it be helpful and even wanted if (assumed, since start-up) non-free, since there is GitHub - Pangoraw/Polars.jl: 🐻 Julia wrapper around the polars library (the expected wrapper for the Rust code, not to be confused with Polar.jl). You are likely limited to data types equivalent to Rust’s so not really limited?
Well that way Julia is neither limited, or any language(?). And there’s also Dagger.jl, and do you rather want to compete with Spark (that is free?) anrather than Polars?
