v0.1.0

First public release of GoVec: a compact vector search engine in Go, served over REST and gRPC from a single static binary.

Highlights

• HNSW with heuristic neighbour selection, plus exact brute-force search; cosine and Euclidean distance
• Scalar int8 quantization: -61% disk and -26% RAM at 100k vectors
• Hybrid dense + sparse search and metadata filtering
• Write-ahead log and atomic snapshots, with crash recovery on startup
• REST and gRPC with identical semantics, including streaming batch insert over gRPC
• Multi-arch container image (linux/amd64, linux/arm64)

Run it

docker run -p 9697:9697 -v govec-data:/data ghcr.io/pradyothsp/govec:0.1.0

REST listens on 9697; gRPC on 9698 when grpc.enabled is true. See the README for the API and configuration.

Known limitations

• Single node, in-memory first
• Filtered HNSW search can return fewer than k results for selective filters
• Hybrid search scores sparse vectors with an O(n) scan
