Lightweight Realtime & Offline Data Storage on Android without a Database
summary
Eclipse Store is a Java/Kotlin persistence engine that keeps live object graphs in memory, stores only deltas as binary snapshots to blob storage (S3/Cloud Blob), and lazy-loads subgraphs on demand. It claims 1000x faster in-memory queries (microseconds vs milliseconds) and huge cost reduction: 250 GB on S3 ≈ $70/year vs $8k–$50k for managed DBs. No annotations or ORM, uses Java Streams for queries, runs on Android/GraalVM and is used in production (Allianz, Fraport luggage scanner).
