Elasticsearch 7.7.0, based on Lucene 8.5.1, introduces several new features and enhancements aimed at improving performance and usability for users. Key updates include asynchronous search capabilities, which allow long-running queries to be executed in the background with progress tracking and partial result retrieval. This feature is particularly useful for searching large datasets, such as those required for regulatory audits or threat hunting. The release also significantly reduces heap memory consumption for time-series data by moving the terms index of the _id field off-heap, enhancing cluster management efficiency. Security improvements include the option to password-protect the Elasticsearch keystore, while the beta release of the Painless Lab in Kibana offers a platform for easier script testing and debugging. Additionally, performance enhancements for time-sorted queries and support for new platforms like Red Hat Enterprise Linux 8 and Windows 2019 are included, alongside the availability of official builds for ARM architectures and the introduction of Elastic Helm charts for Kubernetes deployment.
