About us
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.

OpenSearch × AAIF: Where Search Meets Agents
Freshworks, Freshworks, Block B, SP Infocity, 40, MGR Main Rd, Kodandarama Nagar, Perungudi, Chennai, INChenn-AI, are you ready for what's next? 🚀
OpenSearch and the Agentic AI Foundation are helping shape the future of how intelligent tools and AI agents are built, discovered, and scaled.
Join us for an exciting community gathering featuring talks from hands-on practitioners, industry experts, and community members sharing their knowledge and real-world experiences.
No commercial activity. No product pitches. Just great conversations, practical learning, and open-source goodness.
Talk 1: ODD for Large-Scale Observability
Speaker: Harikrishnan Prabhakar and SivaGnanam Arumugam (Lead Software Engineer at Freshworks)
Running observability at 6 GB/s is a serious scaling challenge - especially when you’re building it entirely on open source. In this talk, we’ll take you behind the scenes of our ~1,500-node OpenSearch and ~300-node Data Prepper deployment processing roughly 400 TB of observability data every day.
We’ll show how we built a full observability platform using OpenSearch, Data Prepper, and OpenSearch Dashboards, extending the ODD ecosystem to support RUM, synthetics, distributed traces, profiling, and alerting without relying on proprietary observability platforms.
We’ll dive into the architectural patterns that made this possible, including pluggable Data Prepper pipelines, custom OpenSearch Dashboards extensions, and S3-backed remote snapshots for reducing cold-storage costs at scale. Beyond the architecture, we’ll share the practical lessons from operating the platform at this scale - including the bottlenecks, trade-offs, and failures that shaped the design. Attendees will leave with concrete patterns for building and extending large-scale observability platforms with the OpenSearch ecosystem, while avoiding vendor lock-in.
Talk 2 : Panchathanthiram: The 5 Agentic AI Foundation Projects
Speaker: Ram Iyengar (Chief Evangelist at Linux foundation)
In Chennai’s first ever AAIF meetup, this talk aims to be an overview of the five Agentic AI Foundation projects. Come learn about how these projects are transforming the workplace. How do these projects help you reimagine the software stack? What is the exact nature of problems these projects are solving? Let’s come together as a community to explore these ideas. And more.
Talk 3: The Marina Mystery
What Really Happens Between Prompt and Production?Speaker: Paranitharan kalaiselvan (Principal Engineer at Comcast)
Agents, MCP tools, models, and downstream services are all coming together quickly—but when something breaks, where do you even start debugging?
In this live, mystery-driven demo, we’ll follow a single agent request across these layers, deliberately introduce failures, and use OpenTelemetry to uncover what really happened.
Attendees will leave with a simple, practical approach to tracing and debugging their own agents end-to-end.Talk 4: Grounding Agentic AI with OpenSearch: How Hybrid Search Powers Production AI Features
Speaker: Priyadarshini Vasanthakrishnan ( Lead Software Engineer) and Anishma Ramani (Senior Software Engineer)
Agentic AI features only work when retrieval is accurate, permission-aware, and fresh—not when an LLM sits beside a vector index. This session shows how hybrid search on OpenSearch forms the foundation for Production AI at Freshworks. We walk through the full RAG lifecycle: event-driven ingestion and indexing on OpenSearch. On retrieval, we cover hybrid search (keyword + semantic + sparse), query rewrite, fusion strategies for precision. We ground these patterns in practical use cases—AI copilots searching native and federated knowledge, email bots answering from KB content, and agent-assist finding similar tickets—showing when hybrid search outperforms semantic-only retrieval and how search becomes the reliable backbone for trustworthy agentic AI.
