Learn about: OpenSearch: The Open Source Path to Vector and Hybrid Search
OpenSearch has become a cornerstone of open source search and observability, empowering developers and organizations to derive meaningful insights from unstructured data at scale. OpenSearch’s vector database supports trillions of vectors and tens of thousands of QPS. As a top-level project under The Linux Foundation, and backed by major brands such as AWS, Uber, IBM and SAP, the project is further cementing its position in the open source ecosystem and the industry at large.
In this session, OpenSearch Ambassador Dotan Horovits (https://www.linkedin.com/in/horovits/) will introduce OpenSearch fundamentals of how to integrate your foundation model of choice, store and process embeddings of various data modalities—whether text, images, audio, video or PDF documents—and use exact and approximate k-NN algorithms to calculate proximity. We’ll look at the journey from lexical search to semantic search, and how OpenSearch combines both approaches in one complete package. We’ll also see important updates from the V3 major release and recent updates around GPU acceleration, MCP servers, agentic AI and more.
