Graft

       

**Graft** is an open-source transactional storage engine designed for efficient data synchronization at the edge. It supports lazy, partial replication with strong consistency, ensuring applications replicate only the data they need. **Core Benefits:** - **Lazy Replication**: Clients sync data on demand, saving network and compute. - **Partial Replication**: Minimize bandwidth by syncing only required data. - **Edge Optimization**: Lightweight client designed for edge, mobile, and embedded environments. - **Strong Consistency**: Serializable Snapshot Isolation ensures correct, consistent data views. - **Transactional Object Storage**: Graft turns object storage into a transactional system—supporting consistent updates to subsets of data at page granularity, without imposing any data format or schema. - **Instant Read Replicas**: Decoupled metadata and data allow replicas to spin up immediately—no replay, no waiting for full recovery. **Use Cases:** - Offline-first and mobile applications - Cross-platform synchronization - Stateless replicas for serverless or embedded environments - Diverse data replication scenarios - Storage and replication for databases **Learn more:** - [SyncConf 2025 Talk](https://www.youtube.com/watch?v=QoKzDyH2MEA) - [Blog Post](https://sqlsync.dev/posts/stop-syncing-everything/) - [Vancouver Systems Talk](https://www.youtube.com/watch?v=eRsD8uSAi0s) - [High Performance SQLite Talk](https://www.youtube.com/watch?v=dJurdmhPLH4) - [Documentation](https://graft.rs) ## Using Graft Graft should be considered **Alpha** quality software. Thus, please contact @carlsverre before using it in production. The easiest way to contact @carlsverre is via Discord on the [orbitinghail server][discord].

[Please see the documentation][sqlite-docs] for instructions on how to download and use it with SQLite. [sqlite-docs]: https://graft.rs/docs/sqlite/ ### Rust Crate Graft can be embedded in your Rust application directly, although for now that is left as an exercise for the reader. You can find the Rust docs here: https://docs.rs/graft ### Other languages? You can use the Graft SQLite extension from any language that has a native SQLite library. Please [see the documentation for details][sqlite-docs]. If you'd like to access the Graft low-level Volume API from a language other than Rust, please [file an issue]!
