By decreasing the default refresh interval from 10 to 5 seconds, newly ingested documents become searchable twice as fast without manual configuration. This improvement applies to both traditional full-text search and vector collections supporting semantic and recommendation-based queries, enhancing real-time data retrieval use cases.
The faster refresh supports applications requiring near real-time search responsiveness such as dynamic content updates and retrieval-augmented generation (RAG) systems. This global update spans all 24 AWS regions where the service operates, ensuring lower latency access to fresh data in diverse workloads.
