OpenSearch 3.0 has been launched as the first major update in three years since it became part of the Linux Foundation. Key features include native support for the Model Context Protocol (MCP), pull-based data ingestion, and gRPC support. Performance improvements allow for faster vector search, boosted by GPU acceleration. Additionally, the upgrade to Apache Lucene 10 enhances performance and efficiency, supporting greater AI workload scalability and enabling configurable indexing and search workloads for optimal performance. This release marks a notable advancement in the OpenSearch project following its fork from Elasticsearch.
The latest version of Apache Lucene offers significant improvements in performance, efficiency, and vector search functionality. These types of improvements pave the way for larger vector and search deployments, enabling AI workloads to scale factorially over time.
This allows indexing and search workloads to be configured independently, ensuring consistent, high-performance operation for each. McIntyre, Singh, and Zhu add: 'Benefiting from underlying HTTP/2 infrastructure, gRPC supports multiplexing and bidi.'
