Amazon OpenSearch Serverless has introduced several new features including kNN Byte vector support, radial search capabilities for Vector collections, and new data types and mapping parameters such as strict_allow_templates, wildcard field type, and kuromoji_completion analyzer.
These enhancements deliver significant benefits for search and analytics workloads. The kNN Byte vector support helps reduce costs through lower memory and storage requirements while improving latency and performance. The additional features like nested fields for storing multiple vectors in a single document and new mapping parameters provide greater flexibility and control in managing search operations without the complexity of infrastructure management.
