Summary

Qdrant hosted its first Vector Space Day in San Francisco on June 11th, 2026, gathering over 350 developers, researchers, and engineers at The Midway. The event featured three tracks: Agents and Memory, Search and Retrieval, and Edge and Robotics. Keynotes included Qdrant's Co-Founder André Zayarni's "We Do It the Hard Way" thesis, tracing its evolution from a 2021 GitHub project to a vector search engine used by enterprises like Bosch and Johnson and Johnson. Speakers clarified Qdrant as a "vector search engine," not a database, built for scale, speed, and resilience, supporting use cases from RAG to agentic memory. Breakout sessions included Neo4j on context graphs for agent memory, HubSpot detailing their Vector-as-a-Service platform managing over 20 billion vectors across 150 clusters, and Arize AI stressing the importance of evaluating retrieval relevance beyond similarity, stating "similarity and relevance are not the same thing." The event concluded with a hackathon, "Think Outside the Bot," awarding \$10,000 in prizes for innovative vector search applications like "MemoryAtlas" for mental health detection.

Key takeaway

For MLOps Engineers managing vector search infrastructure, consider Qdrant's vector search engine for its focus on scale, speed, and resilience. If you are building agentic systems, integrate knowledge graphs to improve reasoning and explainability. Prioritize direct relevance metrics like hit rate and recall over mere similarity when evaluating retrieval systems to avoid silent failures in production. Explore Kubernetes operators for managing stateful vector search deployments to streamline operations and optimize resource use.

Key insights

Qdrant positions itself as a vector search engine, not a database, prioritizing scale, speed, and resilience for evolving AI workloads.

Principles

• Retrieval is a core primitive for AI applications.
• Evaluate retrieval relevance, not just similarity.
• Knowledge graphs enhance agent reasoning memory.

Method

HubSpot migrated from Helm to a Kubernetes operator pattern for Qdrant's stateful lifecycle, reducing cluster spin-up from hours to minutes and cutting resource usage skew by 65%.

In practice

• Pair vector search with knowledge graphs for explainable AI.
• Measure retrieval with hit rate, precision, and recall.
• Use hybrid edge-cloud for on-device robotics control.
