Realm: How I learned to love database again
summary
Compares SQLite and Core Data to Realm with concrete outcomes: replaced a Core Data app and finished conversion in about three hours, avoided Core Data’s failed schema migrations that corrupted shipped data, and gained zero-copy memory mapping for much lower memory use. Describes API specifics (Realm objects, one write transaction at a time, thread confinement), best practices (batch writes, use primary keys to re-query on other threads), and the new Realm Object Server / Realm Mobile Platform (syncs devices, tested to ~10k–100k users).
