The value of not reading

Worked examples, recomputed

Every number the mechanisms quote for this relationship is recomputed from it, so none of them disagrees with it.

• 5 of 200 columns × 1 day of 30 × 3× compression → 3,600×
• $50 at the worst layout, ≈ $0.014 at the best
• pushdown keeps 0.1%: 100 MB moves instead of 100 GB

Where it appears

Each mechanism states it in its own names. The general symbol each name stands for is shown with it.

• Cost Mechanics

  What is metered, and what is the smallest increment you are charged for?

  $$(1-\text{selectivity})\times \text{bytes}\times \text{rate}\times \text{frequency}$$
