Running CPU-intensive tasks in other threads also isnt effective, because of. "https://dezyre.gumlet.io/images/blog/fastapi-projects/FastAPI_Project_For_Asynchronous_CRUD_API_on_Notes.png?w=1242&dpr=1.3", You can define API endpoints that take in transaction data as input and output the fraud prediction. You can simplify the process using tools like Pydantic and SQLAlchemy. FastAPI is used to build APIs (Application Programming Interfaces) using Python programming. The next step is implementing authentication and authorization to ensure only authorized users can access the API and perform CRUD operations. global variables are in the config (e.g.SQLALCHEMY_DATABASE_URI, FIRST_SUPERUSER). This can serve as a good starting point for small to medium projects. heavy calculations, data processing, video transcoding) is worthless since the CPU has to work to finish the tasks, while I/O operations are external and the server does nothing while waiting for that operations to finish, thus it can go to the next tasks.
