Multi Step Processes easy
You are writing a script to process 10,000 images. The script runs on a server that might restart unexpectedly. To ensure you don't have to start over from image #1 after a crash, what should you implement?
- A Increase the server's RAM.
- B Checkpointing (saving the ID of the last processed image to a database).
- C Use a faster CPU to finish before the crash.
- D Store the progress in a global variable in Python/Java.
Answer: B. Checkpointing (saving the ID of the last processed image to a database).
Global variables (D) are lost when a process restarts. Checkpointing saves the state to persistent storage (DB/Disk), allowing the system to resume from the last known good state.
One system design question a day, with spaced repetition so the ones you miss come back.

- A user registration process involves two steps: inserting a row into the 'Users' database table and inserting a row into the 'Profiles' table. If the first insert succeeds but the second fails, the database is left in an inconsistent state. What mechanism prevents this?
- In a multi-step workflow across different services (Order Service -> Payment Service), you cannot use a single database transaction. If the Payment fails after the Order was created, how do you fix the Order state?
- A client app sends a 'Pay $50' request to your API. The server processes the payment but the network response is lost. The client automatically retries the request. What prevents the user from being charged $100?
- A user uploads a large video file that needs to be transcoded (converted), which takes 5 minutes. Why is it bad practice to keep the HTTP connection open while the server processes the video?
