One commit per catalog round trip

Worked examples, recomputed

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

• a 100 ms catalog round trip → at most 10 commits per second
• 50,000 rows/s → at least 5,000 rows per commit

Where it appears

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

• Metadata, Catalog & Lineage

  What can a system prove about its data without reading the data, and how does it know that proof is still true?

  $$1/0.1=10\text{commits per second}$$
