Hi all - I just wanted to announce a low memory footprint FOSS graph db I've been working on (named Slater, after the Archer character). The most common complaint about Graph/GraphRAG DBs is the cost and memory footprint they consume: many depend on holding the whole dataset fully in RAM, which makes them expensive to run.
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

How does "standard Bolt" relate to OpenCypher? Does Bolt support imply OpenCypher support?
