Forces per commit

Worked examples, recomputed

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

• 8 pages × 5 ms = 40 ms per commit
• one log force instead → roughly 8× faster

Where it appears

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

• Persistence & Durability

  When a system says "yes, your data is safe", what exactly has it promised, and what did it have to do to keep that promise?

  $$\text{commit cost}=k\times (\text{cost of one force})$$
