feat(postgres): Add HNSW index and embedding functions support by ruvnet · Pull Request #62 · ruvnet/RuVector

ruvnet · 2025-12-09T02:00:27Z

Summary

This PR fixes the two critical limitations from v0.2.4 by adding complete HNSW index access method support and embedding generation functions to the PostgreSQL extension.

Key Changes

✅ HNSW Index Access Method: Added handler function and operator classes for L2, cosine, and inner product distances
✅ Embedding Generation: Added 10 embedding functions using fastembed-rs/ONNX Runtime for local text-to-vector conversion
✅ IVFFlat Cleanup: Removed unimplemented IVFFlat references (module commented out in source)
✅ SQL Schema: Updated from 89 to 100 functions (810 lines)
✅ Version: Bumped to 0.2.6

Files Changed

SQL Schema:

crates/ruvector-postgres/sql/ruvector--0.1.0.sql - Main schema with HNSW and embedding functions
crates/ruvector-postgres/sql/access_methods.sql - HNSW access method definitions
crates/ruvector-postgres/sql/embeddings.sql - Embedding function declarations

Configuration:

crates/ruvector-postgres/Cargo.toml - Version bump to 0.2.6

Embedding Functions Added

ruvector_embed(text) - Generate embedding from text
ruvector_embed_batch(text[]) - Batch embedding generation
ruvector_embedding_models() - List available models
ruvector_load_model() / ruvector_unload_model() - Model management
ruvector_model_info() - Get model information
ruvector_set_default_model() / ruvector_default_model() - Default model config
ruvector_embedding_stats() - Generation statistics
ruvector_embedding_dims() - Get model dimensions

HNSW Operator Classes

ruvector_l2_ops (default) - Euclidean distance
ruvector_cosine_ops - Cosine similarity
ruvector_ip_ops - Inner product

Test Plan

Extension loads without "could not find function" errors
HNSW index creation works: CREATE INDEX USING hnsw (embedding ruvector_l2_ops)
Embedding functions are callable (models require download at runtime)
Docker image built successfully (477MB)
Published to Docker Hub as ruvnet/ruvector-postgres:0.2.5
Published to crates.io as ruvector-postgres v0.2.6
All 100 functions load correctly in PostgreSQL 17

Verified Functionality

-- Extension loads cleanly
CREATE EXTENSION ruvector;

-- HNSW index creation
CREATE INDEX test_hnsw_idx ON vectors USING hnsw (embedding ruvector_l2_ops);

-- Embedding functions available
SELECT ruvector_embed('hello world');
SELECT * FROM ruvector_embedding_models();

Performance Impact

No Rust code changes: Only SQL schema modifications
SIMD unchanged: Still using avx2, fma, sse4.2 (8 floats per operation)
Image size unchanged: 477MB (same as v0.2.4)

Breaking Changes

None. This is purely additive - adds missing functionality without modifying existing features.

Distribution

Docker Hub: ruvnet/ruvector-postgres:0.2.5 (with fixes)
Crates.io: ruvector-postgres v0.2.6 (with fixes)

Records edge cases found during property testing that cause integer overflow failures. These will help reproduce and fix the boundary condition bugs in distance calculations.

- Fix ScalarQuantized::distance() i16 overflow: use i32 for diff*diff (255*255=65025 overflows i16 max of 32767) - Fix ScalarQuantized::quantize() division by zero when all values equal (handle scale=0 case by defaulting to 1.0) - Bound vector_strategy() to -1000..1000 range to prevent overflow in distance calculations with extreme float values All 177 tests now pass in ruvector-core.

- Change --dimensions from -d to -D to avoid conflict with global --debug - Change --db from -d to -b across all subcommands (Insert, Search, Info, Benchmark, Export, Import) to avoid conflict with global --debug Fixes clap panic in debug builds: "Short option names must be unique" Note: 4 CLI integration tests still fail due to pre-existing issue where VectorDB doesn't persist its configuration to disk. When reopening a database, dimensions are read from config defaults (384) instead of from the stored database metadata. This is an architectural issue requiring VectorDB changes to implement proper metadata persistence.

- Add CONFIG_TABLE to storage.rs for persisting DbOptions - Implement save_config() and load_config() methods in VectorStorage - Modify VectorDB::new() to load stored config for existing databases - Fix dimension mismatch by recreating storage with correct dimensions - Fix test_error_handling CLI test to use /dev/null/db.db path This ensures database settings (dimensions, distance metric, HNSW config, quantization) are preserved across restarts. Previously opening an existing database would use default settings instead of stored configuration.

- memory.rs: Fix random_level() to handle r=0 (ln(0) = -inf) - memory.rs: Fix ml calculation when hnsw_m=1 (ln(1) = 0 → div by zero) - router.rs: Add division-by-zero guard in softmax for larger arrays These edge cases could cause undefined behavior or NaN propagation.

A new hyperbolic attention architecture with significant improvements: ## Key Innovations 1. **Lorentz Model**: Uses hyperboloid instead of Poincaré ball - No boundary instability (points can extend to infinity) - Simpler distance formula 2. **Busemann Scoring**: O(d) attention weights via dot products - 50-100x faster than Poincaré distance computation - Naturally hierarchical (measures "depth" in tree) 3. **Einstein Midpoint**: Closed-form hyperbolic centroid - 322x faster than iterative Fréchet mean (50 iterations) - O(n×d) instead of O(n×d×iter) 4. **Multi-Curvature Heads**: Adaptive hierarchy depth - Different heads for shallow vs deep hierarchies - Logarithmically-spaced curvatures 5. **Cascade Aggregation**: Coarse-to-fine refinement - Combines multi-scale representations - Sparse attention via hierarchical pruning ## Benchmark Results (64-dim, 100 keys) | Operation | Poincaré | LCA | Speedup | |-----------|----------|-----|---------| | Distance | 25 ns | 0.5 ns | 53x | | Centroid | 2.3 ms | 7.3 µs | 322x | ## API ```rust let lca = LorentzCascadeAttention::new(LCAConfig { dim: 128, num_heads: 4, curvature_range: (0.1, 2.0), temperature: 1.0, }); let output = lca.attend(&query, &keys, &values); ``` Files: - lorentz_cascade.rs: Core LCA implementation - hyperbolic_bench.rs: Benchmark comparing LCA vs Poincaré

Empty Transaction Tests - Implemented 10+ critical tests: dirty reads, phantom reads, MVCC, deadlock detection - All 31 transaction tests now passing Addresses issues from: https://gist.github.com/couzic/93126a1c12b8d77651f93a7805b4bd60 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

macos-12 runners have very long queue times (45+ minutes). macos-14 runners can cross-compile x86_64 binaries and have much better availability.

- Published ruvector-core-darwin-x64@0.1.25 with native binary built on macos-14 - Updated ruvector-core to 0.1.26 with darwin-x64 in optionalDependencies - Updated ruvector to 0.1.33 CI runner change: Switched darwin-x64 builds from macos-12 to macos-14 for better availability.

- Removed 3 unimplemented functions: ruvector_gat_forward, ruvector_message_aggregate, ruvector_gnn_readout - Updated Dockerfile to use pre-built SQL file instead of cargo pgrx schema (which doesn't work reliably in Docker) - SQL function count: 92 → 89 (matching actual library exports) - Extension now loads successfully in PostgreSQL 17 with avx2 SIMD support - Docker image: ruvnet/ruvector-postgres:0.2.4 (477MB) Fixes SQL/library function symbol mismatch that caused "could not find function" errors during extension loading.

- Added HNSW access method handler and operator classes - Added 10 embedding generation functions (ruvector_embed, etc.) - Removed IVFFlat references (not yet implemented) - Updated SQL schema from 89 to 100 functions - Fixed 'could not find function' errors on extension load Fixes: HNSW index support, embedding generation availability

Resolved conflicts by: - Keeping version 0.2.6 in Cargo.toml - Preserving SQL schema with HNSW and embedding functions (810 lines, 100 functions) - Keeping HNSW access method implementation - Accepting main's binary .node files for npm packages - Regenerating Cargo.lock with updated dependencies This merge integrates latest changes from main while maintaining all HNSW index and embedding function fixes from this branch.
