Draft outline details

Step by step

  1. Write the forecast chain and assumptions with ranges.
  2. Derive peak RPS and write rate for PostgreSQL.
  3. Planned mistake: size from the daily average. Fix: apply the burst factor and the Black Friday multiplier; the result is several times larger.
  4. Estimate Kafka throughput, partitions, and storage with replication and retention.
  5. Compare with MID load-test limits; name the first bottleneck.
  6. Add headroom and re-planning triggers.
