The first-ever OpenSearchCon India, held in the bustling tech hub of Bengaluru, has wrapped up, leaving the open-source community buzzing with excitement. The two-day conference, which took place from June 3rd to 4th, 2025, brought together developers, DevOps professionals, data engineers, and tech leaders from across the globe to dive deep into the world of search, analytics, and observability.

Hosted by the Linux Foundation, the event was a vibrant showcase of the power and potential of the OpenSearch project. From groundbreaking new features to inspiring community stories, here are some of the biggest takeaways from the conference.

The Future is Vector-Powered: Keynotes Set the Stage

The conference kicked off with a powerful keynote from Pallavi Priyadarshini, Senior Manager at Amazon Web Services (AWS), and Sreedhar Gade, Vice President of Engineering & Responsible AI at Freshworks. Their talk, “From Keyword Search to Vector Powered Insights: The OpenSearch Journey,” set the tone for the event, highlighting the evolution of search technology and the growing importance of vector search and Retrieval-Augmented Generation (RAG) in building intelligent, AI-powered applications.

Another standout keynote was delivered by Fernando Garcia Valenzuela, Head of Engineering at Atlassian, who shared insights into how the software giant leverages OpenSearch at a massive scale. His presentation offered a real-world look at the challenges and triumphs of operating a high-demand search infrastructure.

Hot Topics: AI, Observability, and Scaling to Petabytes

Throughout the conference, several key themes emerged as focal points of discussion and innovation:

• The Rise of AI and Vector Search: Sessions on integrating Large Language Models (LLMs) with OpenSearch, orchestrating multimodal RAG with agentic workflows, and harnessing the power of vector stores for similarity search were packed with attendees eager to explore the new frontier of AI-driven search.
• Observability at Scale: The importance of robust observability in modern, distributed systems was a recurring topic. Experts from companies like Forrester and AWS shared best practices for scaling AI-powered observability and using OpenTelemetry for effortless instrumentation.
• Petabyte-Scale Log Management: A session by Freshworks on their migration from Elasticsearch to OpenSearch, resulting in a 30% cost reduction at a petabyte scale, drew significant attention. It showcased the power and efficiency of OpenSearch for handling massive volumes of data.

Community at the Core

Beyond the technical deep dives, OpenSearchCon India was a celebration of the open-source community. Sessions on contributing to the OpenSearch project, building a more inclusive and diverse tech ecosystem, and strengthening the Free and Open Source Software (FOSS) community in India underscored the collaborative spirit that drives the OpenSearch project forward.

The “Women in Cloud Native” panel was a particular highlight, featuring inspiring stories and a candid discussion about the challenges and opportunities for women in the tech industry.

Looking Ahead

OpenSearchCon India 2025 was more than just a conference; it was a testament to the power of open collaboration and a glimpse into the future of search and analytics. The energy and enthusiasm of the attendees were palpable, and it’s clear that the OpenSearch community in India is vibrant and growing.

As we look to the future, it’s evident that OpenSearch will continue to play a pivotal role in shaping how we interact with data. With a strong focus on AI, observability, and community-driven innovation, the future of open source search is brighter than ever.
