Can you explain what is meant by real-time data processing through streaming technologies?

Processing data in real-time through streaming technologies means continuous reception, processing, and analysis of data immediately after it appears, without significant delay.

In Go, this is often implemented using goroutines and channels, which allow asynchronous and parallel processing of data streams.

Example: if you have a stream of events (for example, messages from users), you can read them from a channel and immediately perform necessary operations — filtering, aggregation, writing to a database, or sending notifications.

This differs from batch processing, where data is collected and processed in large blocks with delay.

Go code example:

ch := make(chan string)

// Goroutine for data processing
go func() {
    for msg := range ch {
        fmt.Println("Processing message:", msg)
    }
}()

// Sending data into the stream
ch <- "New event"
close(ch)
