Unlike the `join` command, `joinp` can process files larger than RAM, is multi-threaded, has join key validation, pre-join filtering, supports [asof joins](https://pola-rs.github.io/polars/py-polars/html/reference/dataframe/api/polars.DataFrame.join_asof.html) & its output doesn't have duplicate columns. However, `joinp` doesn't have an --ignore-case option & it doesn't support right outer joins. |
