Bringing Down the Cost of Your OpenSearch Clusters - Aswath Srinivasan, OpenSearch @ AWS & Priyanshi Omer, Unknown Company
Tuesday June 3, 2025 11:15am - 11:55am IST
Cost for running OpenSearch also always been a huge factor. In spite of OpenSearch being completely open-source and no licensing cost, when you are dealing with terabytes and petabytes of data, cost can quickly stack.

This talk aims to empower OpenSearch users by taking a holistic view using best practices and with practical steps & checklist for reducing the infrastructure cost and to do more with less with OpenSearch regardless of the workload (be it Search/Log Analytics/Observability/Semantic Search).

We'll discuss

1/ Gaining optimal performance from existing resources
2/ How to right size a domain & when to Horizontal scale vs. Vertical scale
3/ How to scale down without impacting performance
4/ How much heap memory is too much or too little and what is the correct vCPU ratio for the given heap memory
5/ When to de-compose larger clusters into smaller clusters Vs. When to aggregate smaller clusters to few larger ones
6/ How to write cache efficient queries, optimize mapping and the index settings
7/ Knobs to improve ingestion and search speed
8/ Budget friendly ways to implement Semantic Search

OpenSearch With Gaia: Building Next-Gen AI-Driven Search and Analytics Workflows - Harish Kotra, Gaia
Tuesday June 3, 2025 12:00pm - 12:40pm IST
This session explores how Gaia’s decentralized AI platform integrates with OpenSearch to create scalable, privacy-preserving solutions for semantic search, generative AI applications, and real-time analytics.

In this session, I intend to demonstrate a use case where Gaia’s federated learning models enhance OpenSearch’s vector database capabilities, enabling dynamic personalization and efficient retrieval-augmented generation (RAG) workflows.

Gaia’s AI Framework: How Gaia’s decentralized architecture complements OpenSearch’s ecosystem, particularly in scenarios requiring data privacy and distributed model training (e.g., healthcare or financial analytics).

Demo a RAG Pipeline: Build a real-world demo/example using Gaia’s language models to generate embeddings stored in OpenSearch’s binary vector indexes (new in v2.19), coupled with OpenSearch Flow for automated pipeline configuration.

Community Impact: A look at how this integration supports OpenSearch’s goal of becoming the preferred backend for generative AI while adhering to open governance principles.

Hacking OpenSearch: Breaking in & Locking It Down - Abhinav Sharma, KodeKloud
Tuesday June 3, 2025 1:40pm - 2:20pm IST
OpenSearch is a powerful search and analytics engine. But many organizations unknowingly expose their OpenSearch clusters, leaving them vulnerable to data leaks, privilege escalation, and even full system compromise. In this session, we’ll look into real-world OpenSearch security flaws, exploit them live, and secure them.

This talk is hands-on - we’ll spin up two OpenSearch environments: one intentionally vulnerable, the other properly secured. You’ll see exactly how attackers break in, followed by a step-by-step hardening process.

The key takeaways from this session will be:
1. Live demonstrations of common attack techniques (unauthenticated access, query injection, privilege escalation, and container compromise)
2. Best practices for securing OpenSearch, including TLS, RBAC, and security configurations

Uber’s Innovations in OpenSearch for a Cloud Native, Serverless Future - Pallavi Priyadarshini, AWS & Shubham Gupta, Uber
Tuesday June 3, 2025 2:25pm - 3:05pm IST
In this session, Uber, a premier member of the OpenSearch Foundation, will share how the unique demands of their low-latency, high-throughput search platform have driven impactful contributions to the OpenSearch project.

The discussion will explore Uber’s collaboration with the OpenSearch community to integrate critical learnings and innovations from their own search platform. Key highlights include the development of a modular, cloud-native architecture with clear separation between readers and writers, a high-performance messaging protocol for inter-service communication, and a pull-based indexing model.

These advancements, along with contributions from the broader OpenSearch community, are shaping OpenSearch into a cutting-edge, serverless open-source search engine tailored for enterprise needs. Join this session to discover how pioneering work from Uber and OpenSearch is paving the way for the next generation of high performance and scalable search technology in open source.

Integrating Graph Context With OpenSearch for Enhanced RAG Application Performance - Satej Sahu, Zalando SE
Tuesday June 3, 2025 3:35pm - 4:15pm IST
OpenSearch is a powerful tool for log storage, analysis, and dashboard reporting. In the context of Retrieval-Augmented Generation (RAG) applications with Large Language Models (LLMs), OpenSearch serves as a vital component, acting as a vector database. This presentation explores an architecture and process flow to integrate graph-based context with OpenSearch, enhancing the correlatability of data and improving the context and performance of search results.

Through experimentation with synthetic data from a travel app, we’ll demonstrate how customer activity data—such as travel points, preferences, and interactions with destinations—can be integrated into OpenSearch. By introducing graph points and correlating them with other data (e.g., maps and historical data), we can provide personalized, more relevant search results for users. Additionally, we’ll compare metrics before and after the introduction of graph context to showcase how it improves search performance and the overall user experience in RAG-based systems.

Hunting Ghosts in the Machine: Real-Time Anomaly Detection for Cybersecurity at Petabyte Scale - Akshat Khanna, Angel One & Unnati Mishra, VMware
Tuesday June 3, 2025 4:20pm - 5:00pm IST
What if your observability tools could predict breaches before they happen? We built a self-learning OpenSearch pipeline that ingests 10M+ logs/sec, detects zero-day threats using unsupervised ML models, and auto-generates incident reports. Learn how we optimized OpenSearch’s anomaly detection plugin to reduce false positives by 60%, integrated threat intelligence feeds, and built a custom Kibana dashboard that even your CISO can love.

Spoiler: We’ll share how a single line of bad regex almost took down our cluster (and how we fixed it).
