OpenSearchCon Europe 2025

Dive deep into the cutting-edge strategies for designing robust, highly available OpenSearch clusters that maintain peak performance even in the face of infrastructure challenges. This session will showcase how to leverage the latest OpenSearch features to create a resilient search & ingestion architecture that can withstand various failure scenarios.
We'll explore the synergistic benefits of recently introduced capabilities, including:

1. Weighted Round Robin: Learn how to optimize request distribution across nodes, ensuring balanced load and improved cluster stability.
2. Gray Disk Detection: Understand how to preemptively identify and mitigate potential disk failures before they impact cluster health.
3. Search & Indexing Backpressure Mechanisms: Master the art of gracefully handling query overloads to maintain consistent search & indexing performance under high demand.


Whether you're managing mission-critical search infrastructure or planning to scale your OpenSearch implementation, this session will equip you with the knowledge to architect highly available clusters that deliver reliable performance in the face of unforeseen challenges.
