Operating an OpenSearch Powered E-commerce Search Engine at Scale

Operating an OpenSearch Powered E-commerce Search Engine at Scale - Lucian Precup & Amine Gani, Adelean What does it take to run a search engine that powers over 1000 e-commerce stores—each with unique catalogs, configurations, and user behaviors? This talk explores the search engine from a DevOps perspective: not as an algorithmic black box, but as a living, evolving platform that must be deployed, monitored, debugged, and optimized at scale. We’ll dive into the operational realities of handling massive index updates, managing search relevance across diverse verticals, and ensuring uptime during traffic spikes. Learn how we approach observability, on-call strategies, and performance tuning for a system where every millisecond counts and every typo matters. This session is for search admins, SREs, and DevOps engineers who want to understand OpenSearch infrastructure beyond the query parser.
