This FLIP has been subsumed by FLIP-498: AsyncTableFunction for async table function support [1]. In the discussion for FLIP-498, we decided to discard FLIP-313 as it has been abandoned for a while.

I hope this is ok for everyone. @Alan might give some timeline when this feature will land?

Cheers,
Timo

We currently use a custom async table source and join it using FOR SYSTEM TIME 
AS OF .... This approach has some challenges, especially when used after 
aggregations .

Introducing support for an async UDTF would allow us to perform the join using 
LATERAL TABLE, which would greatly simplify the query structure and improve 
maintainability.

Kind regards,
Fred Teunissen

I just realized this FLIP has never been voted to pass.

+1 to the FLIP.
This is actually something long overdue. I feel it is even more like a bug
that we need to fix than a feature.

Thanks,

Jiangjie (Becket) Qin
