Elasticsearch 7.10.0, based on Apache Lucene 8.7.0, introduces several innovative features aimed at enhancing performance, storage efficiency, and security capabilities. Notable updates include searchable snapshots, which allow direct searches on snapshots stored on low-cost cloud storage without restoring them, effectively introducing a cold data tier for cost-efficient storage. The release also enhances security functionalities with the Event Query Language (EQL) now in beta, improving the handling of time-series data for observability and threat detection. Performance improvements include a 10% reduction in storage size due to a new field compression technique and a 50% increase in date histogram aggregation speed. Additional features include a point-in-time reader for consistent querying, case insensitivity in queries, support for unsigned 64-bit integers, and specialized version data types for software versioning. Enhancements in the machine learning domain are marked by the introduction of the AUC ROC metric for model evaluation and customizable feature processors in data analytics. With these advancements, Elasticsearch aims to offer a more robust, efficient, and versatile platform for managing large-scale data operations.
