Frequently Asked Questions
What is Amazon OpenSearch Service?
Amazon OpenSearch Service is a managed search and analytics engine based on OpenSearch (fork of Elasticsearch 7.10). The service enables log analysis, full-text search, and application monitoring.
What is the difference between OpenSearch and Elasticsearch?
OpenSearch is a community fork of Elasticsearch 7.10 under Apache 2.0 license. AWS actively develops OpenSearch with features like ML Anomaly Detection and k-NN Vector Search.
When should I use Serverless instead of Managed Clusters?
Serverless for unpredictable workloads and development environments. Managed Clusters for production with constant utilization and fine-tuning requirements.
What is UltraWarm?
UltraWarm is a cost-effective storage tier for historical data. Approximately 85% cheaper than Hot Storage, with slightly higher query latency.
