What are stream processing frameworks?

Imagine you're at a water fountain, and every second, someone drops a coin into it, one after another, nonstop. A stream processing framework is like a smart robot that watches this fountain and does something with each coin as it comes in.

You could say it's the brain behind continuous events, things happening one after another, never stopping. Like your favorite cartoon character who gets excited every time they hear a new joke.

Think of the coins as data, little pieces of information coming in all the time. The robot (or the stream processing framework) takes each coin and does something with it right away, maybe adds it to a pile, counts how many there are, or even sends a message when a certain number comes in.

This is super helpful if you're tracking things that happen all day long, like messages coming into your phone, orders arriving at a store, or even counting the steps you take while playing tag. It helps you keep up with everything happening around you in real time!
