Idem

Idem is an idempotent data flow programming language. It exposes stateful programming constructs that makes things like enforcing the state of an application, configuration, SaaS system, or others very simple.

What does Idempotent mean?

The concept of Idempotent is simple! It just means that every time something is run, it always has the same end result regardless of the state of a system when the run starts!

At first glance this might seem useless, but think more deeply. Have you ever needed to make sure that something was set up in a consistent way? It can be very nice to be able to enforce that setup without worrying about breaking it. Or think about data pipelines, have you ever had input data that needed to be processed? Idempotent systems allow for data to be easily processed in a consistent way, over and over again!
