 Doris 中的一些功能需要使用一些用户自定义的文件。比如用于访问外部数据源的公钥、密钥文件、证书文件等等。文件管理器提供这样一个功能，能够让用户预先上传这些文件并保存在 Doris 系统中，然后可以在其他命令中引用或访问。

-🎉 Version 3.0.2 released now. Check out the 🔗[Release Notes](../releasenotes/v3.0/release-3.0.2) here. Starting from version 3.X, Apache Doris supports a compute-storage decoupled mode in addition to the compute-storage coupled mode for cluster deployment. With the cloud-native architecture that decouples the computation and storage layers, users can achieve physical isolation between query loads across multiple compute clusters, as well as isolation between read and write loads.

 🎉 Version 2.1.7 released now. Check out the 🔗[Release Notes](../releasenotes/v2.1/release-2.1.6) here. The 2.1 version delivers exceptional performance with 100% higher out-of-the-box queries proven by TPC-DS 1TB tests, enhanced data lake analytics that are 4-6 times speedier than Trino and Spark, solid support for semi-structured data analysis with new Variant types and suite of analytical functions, asynchronous materialized views for query acceleration, optimized real-time writing at scale, and better workload management with stability and runtime SQL resource tracking.
