Complex Event Flows in Distributed Systems

What does the title of your presentation mean?

The title is basically the easiest possible use case that I can use to illustrate why we're doing the complicated things that we are doing. It's because in a factory people still use paper, and in thousands of factories across Germany people on the shop floor do not use computers because computers are not reliable enough. Telling people what to do, sending them work orders is done on paper and recording the results is done with a pen on paper. The reason is that the paper works without Wi-Fi, without electricity, and it will remember what you wrote on it. The same is not true for normal apps that connect to a server.

You're basically talking about a queue at each place, and you pass a message to it. It loads it in the queue. They process it and they move it to the next stage.

Something like that. Also, you want to record all sorts of things, when people started and stopped, whether they have checked certain checkmarks or put in measurement values that you do for for quality assurance in a factory. Whatever processes you do when you interact as a human with all the machines that are there.
