OpenDAL
An open data access layer that provides a unified API for interacting with diverse storage services across any language.
What is OpenDAL?
Apache OpenDAL is an Open Data Access Layer that provides a single, consistent API for interacting with over 50 diverse storage services. It abstracts the complexities of different storage backends—including cloud object storage, file systems, databases, and key-value stores—enabling developers to write storage-agnostic applications. This solves the problem of fragmented storage access by allowing applications to work seamlessly across multiple providers and protocols without vendor lock-in.
Developers and engineers building applications that need to interact with multiple storage backends, such as cloud-native applications, data processing pipelines, or multi-cloud storage solutions. It is particularly valuable for teams working in polyglot environments who need consistent storage access across programming languages like Rust, Java, Python, Go, and Node.js.
Developers choose OpenDAL for its unified API that supports an extensive range of storage services through a single interface, eliminating the need to learn and integrate multiple SDKs. Its unique selling point is the combination of broad multi-language support, high performance, and extensible architecture, allowing for consistent and efficient data operations across any storage backend.
