DriftDB, a Time Travel DB Written in Rust

AI Analysis
●●SolidWizardryBig Brain
Time-travel SQL on append-only storage, but PostgreSQL temporal tables already exist.
Strengths
- •Temporal query syntax (SQL:2011) cleanly separates historical snapshots from mutation logic
- •Append-only + immutable sequences prevent accidental data rewrites in audit-critical systems
- •Comprehensive docs and architecture section show genuine thought on constraints (MVCC, WAL, snapshots)
Weaknesses
- •Status: Alpha — core engine works but higher-level features incomplete; production risk
- •Competes with mature temporal features in PostgreSQL and ClickHouse without clear differentiator
Category
Target Audience

PardusDB – SQLite-like vector database in Rust
Using a single-file .pardus format with CREATE/INSERT/SELECT + SIMILARITY queries gives a very familiar developer UX for embedding storage. The combination of graph-based ANN, full transactions, thread-safety, and zero external dependencies is an uncommon and useful engineering combo for local-first AI work; it would win more attention with benchmark comparisons and richer ecosystem integrations (connectors/clients).
