Elastic Stack 8.10 introduces significant enhancements to cross-cluster and vector search, data ingestion, Kibana, and cloud registration, aiming to improve user experiences and streamline operations. Key updates include faster vector search capabilities with increased parallelization, general availability of kNN vector search for up to 2048 dimensions, and improved cross-cluster search (CCS) functionality with more detailed status information. Kibana now offers features such as data drift detection through the Data Comparison view and log rate analysis for both spikes and dips, alongside enhanced multivalue filtering options for charts. Security improvements include a new model for cross-cluster connections using API-based authentication and better integration capabilities through a client certificate-supported Webhook connector. Additionally, Elastic Agent now supports Kafka for streaming application data, and a new synonyms API simplifies synonym management within clusters. These features, available on the Elastic Cloud, aim to enhance data analysis, integration, and security for Elastic users.
