Introduction

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
