What is Fluid?

Fluid is an open source Kubernetes-native Distributed Dataset Orchestrator and Accelerator for data-intesive applications, such as big data and AI applications.

Features

  • Native Support for DataSet Abstraction

    Make the abilities needed by data-intensive applictions as navtive-supported functions, to achieve efficient data access and reduce the cost of multidimensional management.

  • Cloud Data Warming up and Accessing Acceleration

    Fluid empowers Distributed Cache Capaicty(Alluixo inside) in Kubernetes with Observability, Portability, Horizontal Scalability

  • Co-Orchestration for Data and Application

    During application scheduling and data placement on cloud, taking both the app's characteristics and data location into consideration, to improve the performance.

  • Support Multiple Namespaces Management

    User can create and manage datasets in multiple namespaces

  • Support Heterogeneous Data Source Management

    Unify the Data access for OSS, HDFS, CEPH and Other underlayer storages

Key Concepts

Dataset: A set of logically related data that will be used by a computing engine, such as Spark for big data and TensorFlow for AI scenarios. The management of dataset has many metrics, has multiple dimensions, such as security, version management and data acceleration. And we hope to start with data acceleration and provide support for the management of data sets.

Runtime: Security, version management and data acceleration, and defines a series of life cycle interfaces. You can implement them.

AlluxioRuntime: From Alluixo, Fluid manages and schedules Alluxio Runtime to achieve dataset visibility, elastic scaling, and data migration. It is an engine which supports data management and caching of datasets.

Prerequisites

  • Kubernetes version > 1.14, and support CSI
