Forget SQLite and say hello to Realm
summary
Claim: Realm replaces SQLite and Core Data with its own persistence engine rather than an ORM. Implementation details: a C++ core and a zero copy Object Store that yields reads <1 ms for thousands of objects while bulk writes remain slower; benchmarking compares Realm against raw SQLite, DBFlow and CouchDB Lite. Practical tradeoffs: adds ~730 KB APK increase and ~1,750 methods, requires migrations for schema changes, objects are thread‑confined, and encryption plus a Realm Browser and adapters are supported.
