Could you build this?
Partial While an ephemeral file-based or serverless JSON store is simple, building a reliable, ACID-compliant document database that functions per-request without an active daemon requires sophisticated embedded storage engine engineering.
What it would actually take: Building this requires an embedded storage engine in Rust or Go compiled to WebAssembly or lightweight serverless runtimes, operating directly on object storage (S3) or block devices using append-only logs, LSM trees, or SQLite/DuckDB foundations with optimistic concurrency control. The hard challenges involve snapshot isolation, index serialization, and handling concurrent writes across stateless lambdas without a centralized coordinator.
Discussion
1 comment analyzed.
Competitors mentioned: Postgres, Iceberg / Delta / Litestream, Firebase/Firestore
Concerns raised: No cross-collection transactions or joins, Read-cost-heavy at scale (folding log tail per read), S3 Class A operations costs prohibitive at high write volume, Per-collection linearizability only, not global
Feature requests: Export to other databases beyond Postgres, Cross-collection transaction support
