I've been diving into the architecture of real-time data stream analysis lately and noticed there are quite a few technical paths out there, like stream processing frameworks, state management mechanisms, and windowed computation methods. Could any of you folks share what the mainstream tech stack is for real-time data stream analysis at this stage? Or which technical solutions have been successfully implemented in industrial scenarios? I'm starting from scratch here, so any guidance would be greatly appreciated!
Which key technologies are worth paying attention to for real-time data stream analysis?

That’s exactly the point—you can’t avoid the windowed approach, but it’s a double-edged sword. If your data comes with wild load fluctuations (like evening spikes), how do you pick the window size—fixed time buckets or something more dynamic, like a sliding window with adaptive shifts? At our Moscow fintech project, we had to switch from 5-minute tumbling windows to adaptive sliding with a Kafka throughput trigger, otherwise we were losing up to 12% of events at peak times. I’m wondering if this is a common pain point or if we overcomplicated things.
