Executes approximate nearest neighbor (ANN) search on dense vector embeddings using HNSW (Hierarchical Navigable Small World) indexing, enabling sub-millisecond retrieval of semantically similar vectors from billion-scale datasets. The system maintains hierarchical graph structures with configurable layer counts and connection parameters, supporting both L2 and cosine distance metrics with SIMD-optimized distance computation.
Unique: Implements HNSW with C++20 modules for compile-time graph structure optimization and SIMD-vectorized distance computation, achieving 2-3x faster search than naive implementations while maintaining configurable recall guarantees through hierarchical layer navigation.
vs alternatives: Faster ANN search than Milvus for single-node deployments due to zero-copy memory layout and SIMD optimization; more flexible than Pinecone's closed-source indexing through open-source HNSW tuning.
Executes BM25-based full-text search on sparse vector representations of documents, tokenizing text into terms, computing TF-IDF weights, and ranking results by relevance using the Okapi BM25 probabilistic model. The system maintains inverted indices mapping terms to document IDs with frequency statistics, enabling fast boolean and ranked retrieval without dense embeddings.
Unique: Integrates BM25 ranking directly into the database engine alongside vector search, enabling single-query hybrid retrieval without separate Elasticsearch/Solr instances; uses C++20 modules for compile-time inverted index structure optimization.
vs alternatives: More integrated than Elasticsearch + Pinecone stacks because both search types share transaction semantics and metadata; faster than Milvus for text-heavy workloads due to native BM25 implementation vs. plugin-based approaches.
Supports bulk import of vectors and metadata from CSV, Parquet, or JSON files, with automatic schema inference and parallel loading across multiple threads. Export functionality writes query results to files in same formats; import uses buffered writes and batch index updates to minimize latency and memory overhead.
Unique: Implements parallel bulk import with automatic schema inference and batch index updates, minimizing latency and memory overhead; supports multiple file formats (CSV, Parquet, JSON) with format-specific optimizations.
vs alternatives: Faster than sequential inserts because bulk import uses parallel loading and batch index updates; more flexible than Pinecone because Infinity supports multiple file formats and custom schema definitions.
Creates and manages indices on vector and metadata columns, supporting HNSW indices for dense vectors, inverted indices for full-text search, and B-tree indices for metadata filtering. Index creation is asynchronous and can be cancelled; index statistics are maintained for query optimization and can be manually refreshed.
Unique: Implements asynchronous index creation with cancellation support and automatic statistics collection, enabling background index building without blocking queries; supports multiple index types (HNSW, inverted, B-tree) with type-specific optimization.
vs alternatives: More flexible than Pinecone because Infinity exposes index parameters for tuning; more integrated than Milvus because index creation uses standard SQL DDL syntax.
Creates point-in-time snapshots of the entire database including vectors, metadata, and indices, enabling recovery to previous states or migration to other systems. Snapshots are incremental and can be stored locally or on remote storage; recovery is atomic and validates data integrity before committing.
Unique: Implements incremental snapshots with atomic recovery and data integrity validation, enabling efficient backups and point-in-time recovery; integrates with external storage for cloud-native deployments.
vs alternatives: More efficient than full database copies because snapshots are incremental; more reliable than WAL-based recovery because snapshots include validated data integrity checksums.
Optimizes query execution plans using cost-based optimization that estimates operation costs (I/O, CPU, memory) and selects lowest-cost plan. The optimizer considers index availability, data statistics, and filter selectivity to decide between sequential scan, index scan, and hybrid search paths; execution uses pipelined operators for memory efficiency.
Unique: Implements cost-based query optimization for vector databases, estimating costs of vector operations (ANN search, BM25 ranking, fusion) alongside traditional SQL operations; uses C++20 modules for compile-time plan specialization.
vs alternatives: More sophisticated than Pinecone (no query optimization) because Infinity automatically selects optimal execution strategy; simpler than Postgres because vector operations have specialized cost models.
Executes search over multi-vector (tensor) representations where each document contains multiple embedding vectors (e.g., different model outputs or chunked representations), aggregating relevance scores across vectors using configurable fusion strategies (max, mean, weighted sum). The system stores tensors as columnar data structures and applies ANN search independently per vector dimension before combining results.
Unique: Implements tensor search as first-class database primitive with configurable fusion strategies, storing multi-vector data in columnar format for cache-efficient ANN search; unlike external reranking, fusion happens inside the query engine with transaction guarantees.
vs alternatives: More efficient than post-hoc reranking because fusion happens during index traversal; simpler than Vespa's tensor ranking because Infinity abstracts fusion logic while maintaining SQL query interface.
Combines dense vector search, sparse vector (BM25) search, and full-text search in a single query, executing each search path independently and fusing results using configurable strategies (weighted sum, RRF, learned fusion). The query planner routes subqueries to appropriate indices and merges ranked lists while maintaining result deduplication and score normalization across heterogeneous search types.
Unique: Implements hybrid search as a first-class SQL query primitive with query planner support, executing vector and BM25 searches in parallel and fusing results inside the database engine; unlike external fusion (e.g., LangChain), maintains transaction semantics and enables index-aware optimization.
vs alternatives: More integrated than Elasticsearch + Pinecone because both search types share query planning and metadata; faster than sequential searches because vector and BM25 indices are queried in parallel within single transaction.

Queries PostgreSQL information_schema and Supabase metadata tables to dynamically generate schema descriptions, enabling agents to construct valid queries and understand data relationships.
Unique: Queries Supabase's PostgreSQL information_schema directly through MCP tools, enabling agents to dynamically discover and adapt to database schemas without pre-configured schema definitions
vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
