Analytics
CoreAmazon OpenSearch Service
Managed service for deploying and operating OpenSearch clusters and serverless collections for search, log analytics, and related indexed workloads.
Key points
- Use an index designed for search queries, text analysis, and aggregations.
- Preserve an appropriate source of truth when an index is a derived search view.
- Authorize domain or collection access and protect the connection and indexed data.
Best-known use cases
- Full-text and relevance search.
- Indexed application and log analytics.
What candidates often confuse it with
- OpenSearch Service supports indexed search; DynamoDB supports primary-key access patterns.
- OpenSearch Service is not automatically the authoritative relational or transactional store.
Key takeaway
Choose OpenSearch Service for search-specific access patterns, not merely because an application has data.
