Hard50 minPremium Asked at OpenAI

    Start from a key-value store that serializes to JSON, then give it the machinery that makes persistence real: an append-only journal, checkpoints, log compaction, and recovery from a log whose tail was lost mid-write.

    The five steps
    1. Store and serialize 8 min
    2. An append-only journal 10 min
    3. Checkpoints 9 min
    4. Compaction 10 min
    5. Surviving a bad shutdown 11 min
