Slater starts with the premise of a fixed memory budget applied to an LRU cache of what's on disk, then uses ISAM blocks and DiskANN/Vamana/PQ to allow paging the contents of the graphs and vectors you need into that cache. It's designed around read-heavy-write-light cases, and can be backed either by local disk or by S3/GCS buckets with an optional sized local disk L2 cache as well.

Speaks standard Bolt, and is GDPR friendly (encryption at-rest and in-transit). Multi-user-multi-graph with ACLs, Rust-with-forbid-unsafe and NFS-friendly too (no mmaps). It's Apache licensed.

Please give it a try if you get a chance. Would love any suggestions or feedback.

Full disclosure: yes, it was authored by Claude Code, although I provided the storage model and design it used, along with code samples and influences from other open source projects like FalkorDB and Memgraph for Bolt wire-compatibility.

Thanks
