• Dataset Abstraction

  Implement the unified abstraction for datasets from multiple storage sources, with observability features to help users evaluate the need for scaling the cache system.

• Scalable Data Engine

  Offers a unified access interface for data operations with different runtimes, enabling access to third-party storage systems.

• Automated Data Operations

  Provides various automated data operation modes to facilitate integration with automated operations systems.

• Elasticity and Scheduling

  By combining data caching technology with elastic scaling, portability, observability, and data affinity scheduling capabilities, Fluid enhances data access performance.

• Runtime Platform Agnostic

  Supports a variety of environments and can run different storage clients based on the environment, including native, edge, Serverless Kubernetes clusters, and Kubernetes multi-cluster environments.

Dataset: A DataSet is a set of data logically related that can be used by computing engines, such as Spark for big data analytics and TensorFlow for AI applications. Intelligently leveraging data often creates core industry values. Managing DataSets may require features in different dimensions, such as security, version management and data acceleration. We hope to start with data acceleration to support the management of datasets.

Runtime: The execution engine that enforces dataset security, provides version management and data acceleration capabilities. The Runtime defines a set of interfaces to manage DataSets in their life cycle, so the management and acceleration of datasets can be implemented behind these interfaces.

• Kubernetes version > 1.16, and support CSI
• Golang 1.18+
• Helm 3
