Multi Step Processes hard
You initiate a file export job that streams data to S3. The worker crashes halfway through. You have a retry mechanism. What resource leak must you handle?
- A CPU leakage.
- B Database connection leaks.
- C Memory leaks.
- D Orphaned Multipart Upload parts in S3 that are never completed or aborted, costing money indefinitely.
Answer: D. Orphaned Multipart Upload parts in S3 that are never completed or aborted, costing money indefinitely.
If a process dies, it can't clean up external state. In S3, if you start a multipart upload but never finish it, the hidden chunks sit there charging you storage fees until a lifecycle policy cleans them.
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?
- 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 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?
- How does CDC (reading the database transaction log) solve the 'Dual Write' problem better than the Application-level Outbox pattern?
