Vector embeddings are the mathematical foundation of semantic search, recommendation algorithms, and AI agent memory. Storing and querying millions of high-dimensional vectors requires specialized database indexing.

For startups already running PostgreSQL, pgvector provides an exceptional zero-cost starting point, eliminating the need to manage a separate standalone database infrastructure.

For high-scale production systems with hundreds of millions of embeddings requiring sub-20ms HNSW index traversals, dedicated Rust-based engines like Qdrant provide superior throughput and lower RAM consumption.

AVELIO benchmarks and deploys tailored vector infrastructure suited to your platform's concurrency demands and operating budget.

Key Architectural Takeaway
