Table API zipWithIndex

[Flavio Pompermaier]

Hi to all,

is there any plan to support the equivalent of DataSetUtils.zipWithIndex as a select expression in the Table API? is it possible to implement it as an UDF right now?

Best,

Flavio

Hi Flavio,

I guess you are looking for a unique identifier for rows, right?
Currently, this is not possible in Table API. There, we only support
UUID(). Once the Table API has been enhanced to be more interactive, we
might support such features.

Regards,
Timo
