Is there experience writing programs with multithreading and asynchronous operations? Has there been support for developing distributed systems?

In Go, concurrency is implemented through goroutines and channels, which allows for efficient writing of asynchronous and concurrent code. For example, to process data in parallel, you can launch multiple goroutines and synchronize them via channels.

Support for developing distributed systems often includes using RPC, gRPC, message exchanges through queues (e.g., Kafka), as well as managing state and data consistency between nodes. In Go, contexts (context.Context) are used for managing the lifetime of requests and canceling operations.

An example of a simple goroutine with a channel:

func worker(ch chan<- int) {
    // Some work
    ch <- 42
}

func main() {
    ch := make(chan int)
    go worker(ch)
    result := <-ch
    fmt.Println("Result:", result)
}
