Slater – Low-memory graphdb designed for read-heavy graphs
Summary
Slater is a low-memory graph database that serves large graphs from on-disk generations with a fixed RAM cache and a writeable LSM layer. It exposes Bolt compatibility with existing Neo4j drivers, supports vector search alongside the graph, and offers multiple storage backends (FS, S3, GCS) for read-heavy workloads with durable writes. The article covers architecture, writable layer details, and deployment considerations for large-scale knowledge graphs.
