Django export memory exhaustion
An AI assistant wrote this Django view to export every order with its line items to CSV. It works fine in dev. In production the endpoint times out and the worker is OOM-killed.
Identify both performance problems and rewrite the data access.
Implement
compare_export_cost(order_count: int, chunk_size: int) → list[int]Examples
in
[1000,200]out[1001,1000,10,200]in
[0,500]out[1,0,1,0]in
[1,500]out[2,1,2,1]What a strong answer looks like
Treat the AI’s output as a draft to verify, not an answer to trust. Name the specific flaw and the input that triggers it, say how you’d catch it (tests, edge cases, reading critically), and how you’d re-prompt or decompose to get it right.

Vibe & agentic: describe the solution in plain language (or narrate it) and the coach grades your approach.
Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
Run or narrate your approach, then ask the coach.
