Elastic 7.12 introduces several significant enhancements across its Enterprise Search, Observability, and Security solutions, all integrated within the Elastic Stack, comprising Elasticsearch and Kibana. This release offers schema on read as a generally available feature, allowing users to create schemas at query time for greater flexibility and reduced time-to-value. The frozen tier, now in technical preview, enables cost-effective searching through object stores like Amazon S3, while autoscaling in Elastic Cloud automatically adjusts resources to maintain performance. In Elastic Enterprise Search, architectural improvements enhance storage efficiency and indexing speed, while Elastic Observability introduces a new correlation capability to streamline application performance analysis. Elastic Security benefits from analyst-driven correlation using Event Query Language (EQL) to improve threat hunting and investigation, and the Elastic Agent now includes behavioral ransomware prevention. These features collectively enhance the flexibility, efficiency, and security capabilities of the Elastic Stack, providing users with improved data management and analysis tools.
