How do cold starts affect real-time stream processing?

Cold starts hurt latency for the first events in a new burst. If your stream has low, sporadic traffic, each new batch may trigger a cold start, adding 1 to 5 seconds of latency. For true real-time processing, you need provisioned concurrency, which adds cost and management overhead.
