Flask provides a signal (signals) function, which is a message distribution mechanism. Similar to hooks (Hooks). Using the signal function can reduce the coupling of the program and decompose the complex business model. For example, after updating the product data, you can send a signal. When there is a function to process the product data, the signal can be captured for processing. For example, to create a product cache, or to update the search index
