FanIn
Multiple independent inputs/sources converge into a single downstream consumer or aggregate result.
Why we need this / what value this brings
Lets you combine results from multiple independent sources into one coherent output, without each source needing to know about the others.
When to use this
When a single response/result genuinely needs input from more than one independent source.
How to use or implement this
Fire off the parallel calls, wait for all (or a timeout) to resolve, and decide explicitly what happens if one source fails or is slow — don't let one straggler block the whole aggregation indefinitely.
Research questions
- Aggregating results from several parallel provider-availability checks into one combined search-results response.
- Collecting PIV results (and their AI summaries) back from 1000s of devices into one rollout status report is fan-in — what happens to the aggregate if 3 of the 1000 devices never respond?
