OpenSearch at Scale: Architecting High-Performance Distributed Search Solutions for Enterprise Data Retrieval

Chansarkar, Anupam (2025) OpenSearch at Scale: Architecting High-Performance Distributed Search Solutions for Enterprise Data Retrieval. World Journal of Advanced Research and Reviews, 26 (2). pp. 2088-2095. ISSN 2581-9615

This technical guide explores the implementation of OpenSearch as a high-performance, distributed search solution for organizations requiring millisecond response times with large-scale datasets. The article examines architectural considerations for optimal performance, including strategic approaches to shard configuration, memory allocation, and replication design based on write frequency patterns. It details effective data modeling practices, emphasizing the importance of appropriate data typing, text analyzers, and keyword normalization to enhance search capabilities. The guide further addresses methodologies for continuous optimization through query pattern analysis and provides a framework for production monitoring to maintain performance at scale. By following these evidence-based recommendations, engineering teams can develop robust search infrastructures that deliver consistent, high-speed access to critical data while effectively managing resources.
