Event stream processing

Event Stream Processing is like a type of computer programming where a computer looks for patterns in a series of events. To put it more simply, it's like a game of 'Simon Says,' but with a computer. An event is like when Simon (in this case, your computer) says "press the red button," and you do so. Your computer is looking for a certain pattern of events, like when you press the red button and then the blue button after. Once your computer finds this pattern, it can do something, like send a message to someone.
