Re: [DISCUSS] Add Side Input/Broadcast Set For Streaming API

[Gábor Gévay <gg...@gmail.com>]

Hello,

I am also interested in this feature for a paper that I'm writing.

"update precondition" that would be expressible by a stateful UDF that
makes its decisions from looking at the elements of the main stream.

Best,
Gábor
