Tee 🌱 ## Why learn these patterns?  ## Fan-in ## ## 1 ## Fan-in Pros - Simplifies aggregation - Enhanced throughput Cons - Potential bottleneck Use cases - API response aggregation - Log aggregation ## Fan-in (Example)  fan-in (multiplex) output channel with combined result ## Fan-out write ![Image](/uploads/documents/a/4/8/4/a48483b335d535abf6e480cccb56024f/p7_1

over channels — Building channel producers — Pipelines — Prime numbers with pipeline — Fan-out — Fan-in — Buffered channels — Channels are fair — Ticker channels ## Channels (experimental) Deferred values consumeEach always consumes (cancels) the underlying channel on its normal or abnormal completion. ## Fan-in Multiple coroutines may send to the same channel. For example, let us have a channel of strings

channels. From the last example, we can find that, with the help of aggregators, it is easy to implement fan-in and fan-out for the number of workers for a specified module. In fact, we can use a simple channel
