What we’re about
This is a group for anyone interested in search engineering, open source search technology, and search relevancy in the Chennai area. If you’ve used or are interested in OpenSearch, you’re in the right place!
All skill levels are welcome. Even if search is just a small part of your day-to-day duties, come learn and connect with other smart engineers. We cover and welcome talks on topics including: search, logging, log analytics, AI, and data visualization.

First OpenSearch Project Meetup: Search, Observability & Beyond
IBM INDIA PRIVATE LIMITED, 5th Floor, Unit 3, Pinnacle Building, Ascendas IT Park, CSIR Road, Taramani, Chennai - 600113, Chennai, INWe’re excited to announce the first-ever OpenSearch Project Meetup in Namma Chennai! 🎉
Join us for an engaging session where we’ll dive deep into the world of search, observability, security and AI Agents — and discover how OpenSearch is powering modern applications.
Whether you’re a developer, student, or tech enthusiast, this meetup is a great chance to learn, connect, and exchange ideas.
📢 Agenda & Speakers:
1. Vector DB 101 With Open Search
Speaker: Ram Iyengar - Chief Evangelist at Cloud Foundry Foundation
Building AI-powered applications requires more than just a model; it requires a robust retrieval strategy. This talk dives into OpenSearch’s native vector search capabilities, showing you how to turn a standard search engine into a powerful Vector Database.
We will cut through the noise and focus on implementation: how to generate, store, and retrieve vector embeddings right alongside your existing dataset. Whether you are building a Retrieval-Augmented Generation (RAG) chatbot, a semantic search engine, or a recommendation algorithm, you will leave this session understanding how to use OpenSearch to deploy efficient, scalable AI solutions without managing a new piece of infrastructure.
2. RAG in Action: Building Smarter AI Systems with OpenSearch
Speaker: Madhavan Kidambi - Software Architect, IBM
A hands-on look at building production-ready RAG pipelines with OpenSearch. We’ll cover hybrid retrieval (BM25 + vector), metadata-aware search, relevance tuning, and end-to-end observability. See how OpenSearch solves many limitations of standalone vector databases and why it’s an ideal foundation for real-world RAG applications.
3. From AWS Elasticsearch to AWS OpenSearch — A Real-World Journey of Scaling, Sharding, Stability and Cost Optimization
Speaker: ManojKumar G and Ragavendra Vigneshwaran, Site Reliability Engineering Professional, IBM
1. Business Case & Migration Strategy: Inevitable shift from Elasticsearch 7.10 to OpenSearch 2.15 to avoid end-of-support risks, phase-wise zero-downtime upgrades (inline, blue-green, parallel, snapshot+inline) across environments.
2. Achieving SLA & Cost Goals: Maintained zero downtime and SLA during migration; optimised costs via shard reallocation, node reduction, and static index templates.
3. OpenSearch Storage & Performance Tuning: Migrated ILM to ISM with size/age-based rollover policies; resolved Fluentd backpressure data loss via S3 → SQS → Vector.dev buffer, enabling zero log loss and further node consolidation.
4. Serverless Adoption: Introduced AWS OpenSearch Serverless with blue-green deployment for additional cost optimization and scalability.
