>The event store and the cache are both part of the same system, and it's this whole system that is "eventually consistent". Then every single system of the face of the earth at a high enough level has a consistency issue. Just go to the level of the full client and backend system using web browsers. You don't refresh the browser you of course will eventually have a "consistency" issue. Usually when they refer to this stuff it's referring to the source of truth: The database. When you shard the database into two synchronizing copies, you increase the availability with a second copy but that leads to the potential for both copies to be inconsistent.
