Amazon OpenSearch Service introduced two new Cluster Insights: Suboptimal Sharding Strategy detects uneven data shard distributions causing workload imbalance, while Cluster Overload monitors resource utilization that may throttle requests. These features offer detailed identification of affected components and actionable recommendations for mitigation.
Previously, users had to manually analyze metrics to diagnose such issues; the new insights automate early detection and guidance, improving operational efficiency. The enhancements are available at no extra cost for OpenSearch versions 2.17+ across supported regions, reflecting AWS's ongoing efforts to improve managed search and analytics services.
