CosmosDB consistency modeling: We needed to specify CosmosDB's client-facing consistency semantics. The anti-pattern would have been modeling the distributed database engine, which would have caused an immediate state-space explosion and an unreadable spec. Instead, we modeled just the "history as a log" abstraction for client-facing behavior. The inner details of the database were "environment"; irrelevant to what we were trying to reason about. We used sort-merge to capture the internals of replication, and a read index to model consistency. This way five consistency levels became clear predicates over operation histories.

There is a sobering footnote to the easy wins. After completing Rogue and Hack, I had high test coverage numbers: 93%, 97%. The projects looked done. Then a friend’s email made me look more carefully, and I discovered that many of those tests were a figleaf.
