About Release 8.0.0
This site contains documentation for HPE Data Fabric release 8.0.0, including installation, configuration, administration, and reference content, as well as content for the associated ecosystem components and drivers.
8.0.0 Installation
This section contains information about installing HPE Data Fabric software. It also contains information about how to migrate data and applications from an Apache Hadoop cluster to a HPE Ezmeral Data Fabric cluster.
8.0.0 Upgrade
This section describes how to upgrade HPE Data Fabric software.
8.0.0 Data Fabric
HPE Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
- HPE Data Fabric File Store
  HPE Data Fabric File Store is a distributed file system for data storage, data management, and data protection. File Store supports mounting and cluster access via NFS and FUSE-based POSIX clients (basic, platinum, or PACC) and also supports access and management via HDFS APIs.
- HPE Data Fabric Object Store
  The HPE Data Fabric Object Store is a native object storage solution that efficiently stores objects and metadata for optimized access.
- HPE Data Fabric Database
  HPE Data Fabric Database is an enterprise-grade, high-performance, NoSQL database management system that you can use for real-time, operational analytics.
  - Architecture
    HPE Data Fabric Database is an enterprise-grade, high performance, NoSQL (“Not Only SQL”) database management system. You can use it to add realtime, operational analytics capabilities to big data applications. As a multi-model NoSQL database, it supports both JSON document models and key-value data models.
  - Data Models
    HPE Data Fabric Database can be used as both a document database and a column-oriented database. As a document database, JSON documents are stored in HPE Data Fabric Database JSON table. As a column-oriented database, binary files are in stored HPE Data Fabric Database binary tables.
  - Secondary Indexes
    Beginning with release version 6.0, HPE Data Fabric Database JSON natively supports secondary indexes on fields in JSON tables. Indexes provide you with flexible, high performance access to data stored in HPE Data Fabric Database.
  - Change Data Capture
    The Change Data Capture (CDC) system allows you to capture changes made to data records in HPE Data Fabric Database tables (JSON or binary) and propagate them to a HPE Data Fabric Streams topic.
  - Table Replication
    You can replicate data in one table to another table that is in the same cluster or in a separate cluster. This type of replication is in addition to the automatic replication that occurs with table regions within a volume.
    - Modes of replication
      Describes the asynchronous and synchronous modes of table replication.
    - Supported replication topologies
      Lists the primary-secondary and multi-master replication technologies.
      - Primary-Secondary Replication
        In this topology, you replicate one way from source tables to replicas. The replicas can be in a remote cluster or in the cluster where the source tables are located.
      - Multi-Master Replication
        In this replication topology, there are two primary-secondary relationships, with each table playing both the primary and secondary roles. Client applications update both tables and each table replicates updates to the other.
    - Gateways for Replicating HPE Data Fabric Database Tables
      In HPE Data Fabric Database table replication, HPE Data Fabric Database replicates updates to tables (binary and JSON) on source Data Fabric clusters to replicas of those tables on destination Data Fabric clusters. Gateways are services that receive these updates and apply them to the replicas. These gateways also propagate updates from JSON tables to their secondary indexes.
    - Replica Autosetup for HPE Data Fabric Database Tables
      The option to automatically set up table replication, also known as replica autosetup, performs the steps to set up and start the replication of HPE Data Fabric Database binary table and HPE Data Fabric Database JSON tables. The replica autosetup option is available through the Control System and maprcli commands.
    - Table Replication States
      The replication state indicates when table replication is in progress and displays the status of operations related to replica autosetup.
    - Order of Writes at Replicas
    - Security and Replication
      Describes how to replicate data between secure clusters.
    - Licensing
      Describes the licensing requirements for Data Fabric.
  - Gateways for Indexing HPE Data Fabric Database Data in Elasticsearch
    As of release version 6.0, HPE Data Fabric Database Elastic Search integration capability is deprecated and no longer available in the HPE Data Fabric Database product.
- HPE Data Fabric Streams
  HPE Data Fabric Streams brings integrated publish and subscribe messaging to the HPE Data Fabric.
- HPE Ezmeral Unified Analytics
  Describes the HPE Ezmeral Unified Analytics Software and provides a link to more information.
- Kubernetes Interfaces for Data Fabric
  This section describes the Kubernetes Interfaces for Data Fabric, which include the Container Storage Interface (CSI) driver for multiple container-orchestration systems, and the FlexVolume driver for Kubernetes.
- Cluster Management
  Provides a synopsis of the various cluster components and their management.
- Performance
  Describes how to tune system performance, manage RDMA, and optimize CLDB tables.
- Security
  Provides an overview of the Data Fabric security features.
- YARN
- Client Connections
  The following sections describe how a client connects to local and remote Data Fabric clusters.
8.0.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
8.0.0 Development
This section contains information related to application development for Ezmeral ecosystem components and HPE Data Fabric products, including the file system, Database (Key-Value and JSON), and Event Streams.
Other Docs
This section contains release-independent information, including: Installer documentation, Ecosystem release notes, interoperability matrices, security vulnerabilities, and links to other Data Fabric version documentation.
Glossary
Definitions for commonly used terms in MapR Converged Data Platform environments.

Supported replication topologies

Lists the primary-secondary and multi-master replication technologies.

There are two types of basic topologies that you can use for your replication scenarios: primary-secondary replication, with which you can construct several different types of more complicated topologies, and multi-master replication.
