OpenSearchCon India 2026

In this talk, we will share our experience building a highly available, multi-tenant, multi-AZ ListView platform on OpenSearch that powers large-scale list and filter experiences for near real-time dashboards.

The session will cover how we designed a fault-tolerant and cost-efficient architecture capable of delivering low-latency queries and high-performance filtering at scale. Using real-world examples from operating OpenSearch at Freshworks, we will walk through practical lessons from building an internal DSL to simplify OpenSearch adoption across teams, designing scalable ETL-driven indexing pipelines, handling concurrent updates & deletes, enabling tenant-level horizontal scaling, and managing dynamic field growth in multi-tenant environments.

This talk will highlight architectural patterns, trade-offs, and operational insights from running OpenSearch in a production SaaS environment. Attendees will gain practical guidance on building reliable, scalable, and performant search systems for large-scale filtering and analytics workloads.
