👉 Non-persistency is a concept in computer science and software engineering that refers to the inability of an algorithm or system to persist across multiple executions. In other words, it means that even after the execution of one iteration of the algorithm or system has completed, the results are not returned to the same state as when the initial iteration was performed. This can lead to a situation where the system behaves differently on subsequent executions, which is known as non-persistence. Non-persistency can be caused by
