Unified Database
Alopex DB
1 File, 5 Modes, Infinite Scale
Same data file scales seamlessly from embedded → server → cluster. No data conversion or migration pain when scaling up—a rare capability only ultra-versatile products like Redis can offer. Raft-based KVS as core with SQL, vector search, and graph ETL in one engine.
Same data file from embedded to cluster. Raft-based KVS + SQL + Vector + Graph ETL in one engine.
- Deployment Modes
- 5
- Data Models
- SQL+Vector+Graph
Key points
- Same data file across all 5 modes, no migration required
- Raft-based KVS with SQL, Vector, and Graph ETL integrated
- Zero code changes to scale, 4 systems consolidated into 1
Challenge
The pain of ever-growing DB products for different needs and scales
Application development requires various data models and scale forms depending on use cases and project size—embedded DBs like SQLite, vector search engines, RDBs, database clusters, and more.
- Separate products, separate connection methods, separate development
- Separate setup and infrastructure management for each product
- Architecture redesign and data conversion when scaling—an excruciating ordeal
Alopex DB uses the same data file to scale seamlessly from embedded to cluster. Unlike typical DB products that require painful data conversion and migration when switching, Alopex DB eliminates this entirely. Raft-based KVS as core with SQL, vector search, and graph ETL in one engine.
Currently in Pre-Alpha development. Bug reports and feature requests are welcome via GitHub Issues.
Raft-based KVS + SQL + Vector + Graph ETL = One Engine
Alopex DB uses the same data file from embedded → server → cluster with seamless scale-up. Enables 'scale without data conversion'—a capability only ultra-versatile products like Redis offer. Raft-based KVS as core with SQL, vector search, and graph ETL in one engine.
- Same data file across all 5 deployment modes
- No data conversion or migration when scaling
- Raft consensus for strongly consistent distributed KVS
- Data conversion
- None
- Code changes to scale
- 0
Capabilities
Five Modes, One Engine
Same data file across all modes. Switch topologies based on operational needs without data conversion.
