Previously capped at 100 results, Amazon S3 Vectors increased the query limit to 10,000 nearest neighbors, facilitating more comprehensive multi-stage processing pipelines. This update supports reranking, deduplication, and aggregation workflows to improve final output relevance.
Pagination allows immediate processing of early results while fetching remaining data, with a modest additional fee for data beyond 512 KB per query. Available across all AWS regions serving S3 Vectors, this extension improves scalability though incurs data usage costs rather than changing underlying search algorithm performance.
