I just tried DuckDB for the first time and I liked this syntax:

CREATE VIEW nation AS SELECT * FROM read_parquet('/mnt/bigdata/tpch/sf10-parquet-float//nation/*.parquet')

This is much easier than CREATE EXTERNAL TABLE.

In Databricks SQL dialect, they support

SELECT * from json.`s3:/foo/bar/table/
