Six short films on what happens to data the moment it stops fitting on one machine: the forced choice, the dial, taste, the cache, the branch library, the shard. The first wing of Learning Maps, the durable principle under each rented AWS label.
The Forced Choice is Episode 1 of Learning Maps, a new Napkin Films series that turns system design into story. A storm takes down the phone line between two librarians, and what happens next is the deepest fact in distributed systems: the CAP theorem, its honest twin PACELC, and the trade every database has already made. Hand drawn on a napkin, narrated by two cloned voices, scored with a 14 Hz focus layer. CC BY 4.0.
