Databricks 增强了其 Feature Store，为机器学习模型提供亚秒级新鲜度，满足了欺诈检测和个性化等应用对实时数据的需求。更新后的 Feature Store 允许数据科学家一次定义特征，并在批量和实时管道中进行部署。它利用 Apache Spark Real-Time Mode、Lakebase 和 Model Serving，实现了从通过 Apache Kafka 进行数据摄取到特征可用性的端到端 p99 延迟为 200 毫秒。 AI

影响通过降低特征延迟，实现更具响应性的实时 ML 应用。

排序理由这是对 Feature Store 的产品更新，而不是核心 AI 模型发布或研究。
