base on Apache OpenDAL: One Layer, All Storage. # Apache OpenDAL™: *One Layer, All Storage.* [](https://github.com/apache/opendal/discussions) [](https://opendal.apache.org/discord) OpenDAL is an Open Data Access Layer that enables seamless interaction with diverse storage services. OpenDAL's development is guided by its vision of **One Layer, All Storage** and its core principles: **Open Community**, **Solid Foundation**, **Fast Access**, **Object Storage First**, and **Extensible Architecture**.
