Amazon OpenSearch Serverless now updates its default refresh interval to 5 seconds for both search and vector collections. The refresh interval decides how fast newly added documents become searchable. The change lowers the previous 10‑second default, so data appears in results twice as quickly without any user configuration. It applies automatically to the next‑generation service in all 24 regions where the product is offered.
Why it matters
Developers building real‑time search or AI‑driven retrieval systems will see fresher results sooner, improving relevance for rapidly changing data.
