In the database drivers of different languages, they usually take a DSN format to connect different database backends.

Like the followings:

• JDBC: jdbc:clickhouse://xxx.myclickhouse.intra.com:8123
• Go SQL Driver: user:password@tcp(127.0.0.1:3306)/db?charset=utf8mb4

Maybe we could also get a DSN like format in opendal? The DSN format may have some benefits:

• allows connecting to different providers in a unified connection format, every one speaks one URL-like string
• easy to write config files, just one-liner instead of multiple parameters
• easy to embed in program logic, likewise SELECT * FROM read_parquet("s3://mybucket.com/file.parquet?token_file=/var/token/access-token")
