❓ Frequently Asked Questions
How does Amazon OpenSearch Service differ from Amazon CloudWatch Logs?
CloudWatch Logs is primarily for collecting and storing logs for basic auditing. OpenSearch is used for advanced analysis, providing full-text search and visualization tools to find specific errors across massive datasets.
When should I choose OpenSearch over a standard relational database like Amazon RDS?
Choose OpenSearch when you need full-text search or real-time log analysis. While RDS is great for structured data and transactions, it cannot match the speed of OpenSearch for unstructured text searches.
