[Datafusion] Support for TPC-H

Hi there,

Happy holidays. Quick question... does DataFusion support all of the TPC-H queries now?

Also, are window functions supported?

Regards,

And yes, window functions are supported, with various sized windows

Hi Olo,

To my knowledge, we support all the TPC-H queries in parsing, planning and
executing, which is tested in CI.
Window functions are supported.

The answers of a few queries are slightly different, as decimal support has
some issues and we're using floats instead. It might be possible some of
those might be fixed. There is a epic over here tracking decimal support
https://github.com/apache/arrow-datafusion/issues/3523

Enjoy the holidays!

Best regards,

Daniël Heres
