Hi @prange,
You could use use
:
Docs: DataStream..use
outerStream.use(stream => { // this is the same stream as outerStream
const state: S = new State();
const out = stream.map(value => someStateMapper(value, state));
return out;
})
I think you could also try DataStream..reduceNow, but that depends on the use case.
@f1ames @jan-warchol @ErykSol - guys, while working on the new version 5 interface, take a look at this. :)

@prange Could you provide a specific example? It would make it easier to reason about how this should work.

I'll close this as a stale issue. @prange if you'd like to follow up - reopen this issue, or perhaps reach out to me and @jan-warchol on Scramjet's Slack
