I've written a fair bit of PySpark code and Polars's syntax feels fairly similar, but it also offers a limited SQL dialect.

Although only experimental and probably off topic to the discussion, it's worth mentioning DuckDB also provides a Spark API implementation.

And while on the subject of syntax, duckdb also has function chaining
