## AI overview

Blinkit describes its OpenSearchCon India 2026 keynote, including its migration from a single OpenSearch cluster to a multi-cluster architecture, the production challenges encountered, and the trade-offs and lessons shared with the community.

## Source excerpt

A few weeks ago, we spoke at OpenSearchCon India about how we make search fast and reliable at scale at Blinkit. I'm Harshit, from the Search Engineering team at Blinkit, and this year we got to speak at OpenSearchCon India at the Jio World Convention Centre in Mumbai. In this post, I'll walk you through our talk, the conversations that followed, and what our team took away from being part of the OpenSearch community in a more active way this year. First Day : Keynote by Blinkit The highlight of this year's conference for our team was the opportunity to deliver a keynote session at OpenSearchCon, organised by the Linux Foundation. Along with my fellow engineer Bharti Sawaria we walked the audience through our journey of migrating from a single OpenSearch cluster to a multi-cluster architecture. We shared the challenges we faced, the solutions that failed in production, and our key learnings for the community. We also discussed Blinkit's growing scale & the trade-offs we made during our migration. To provide context for our global audience, we framed the talk around the sheer scale at which we operate, highlighting the "breaking point" where we realised a single cluster could no longer handle our needs.

Many of whom are dealing with similar scale and freshness challenges, openly sharing what's worked and what hasn't. That kind of unfiltered peer exchange is hard to replicate online. Our team attended multiple breakout sessions and had several great discussions with engineers from Uber, Freshworks, Oracle, and others. A few sessions stood out enough to flag once recordings are
