Features

  • Dataset Abstraction

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

  • Scalable Cache Runtime

    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

    Enhances data access performance by combining data caching technology with elastic scaling, portability, observability, and data affinity-scheduling capabilities.

  • 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.

Key Concepts

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 Runtime enforces dataset isolation/share, provides version management, and enables data acceleration by defining a set of interfaces to handle DataSets throughout their lifecycle, allowing for the implementation of management and acceleration functionalities behind these interfaces.
