8.0.0 Data Fabric
HPE Data Fabric is the industry-leading data platform for AI and analytics that solves enterprise business needs.
8.0.0 Administration
This section describes how to manage the nodes and services that make up a cluster.
- Working with Multiple Fabrics Using the Data Fabric UI
  This section describes how you can get started learning about, installing, and using the HPE Data Fabric.
- Administering Users and Clusters
  Lists topics that help manage a Data Fabric cluster.
- Administering Nodes
  Provides a synopsis of managing nodes in a cluster.
- Administering Volumes
  This section provide information about how to organize and manage data using volumes, a unique feature of HPE Data Fabric clusters.
- Administering Files and Directories
- Administering Tables
  Administration of the HPE Data Fabric Database is done primarily via the command line (maprcli) or with the Managed Control System (MCS). Regardless of whether the HPE Data Fabric Database table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. HPE Data Fabric Database administration is associated with tables, columns and column families, and table regions.
  - Managing Tables
    HPE Data Fabric Database supports two types of table: binary tables and JSON tables. This section covers how to create, edit, and delete tables, as well as how to set parameter values, display parameter values, grant permissions and access, replicate tables, and more using the Control System and the CLI.
  - Managing Column Families and Columns
    This section covers overviews of column families in binary tables and JSON tables, how to create column families, alter them, delete them, set permissions on them, and set and display parameter values.
  - Managing Column Family Fields and Field Permissions for JSON Tables
    This sections covers details for working with column family fields. Column family fields can be added to any existing JSON table, and column families comprise optional fields.
  - Managing Table Replication
    This section contains topics about setting up table replication and administering existing replicas.
  - Managing Secondary Indexes
    Describes how to manage secondary indexes, including adding, deleting, and listing indexes, setting up your cluster for querying, and troubleshooting index usage.
  - Administering Change Data Capture
    This topic covers the Control System and maprcli tools for managing the Change Data Capture (CDC) feature.
    - Setting Up CDC
      Describes the requirements and how to set up Change Data Capture (CDC).
    - Managing Table Changelogs
      Describes how to manage CDC table changelogs through the Control System and maprcli.
      - Adding a Change Data Log
        Explains how to add a change data log using the Control System and the CLI.
      - Viewing the List of Change Logs
        Explains how to view the list of change logs using the Control System or the CLI.
      - Viewing Change Log Information
        Explains how to view information about a specific change log using the CLI.
      - Editing a Change Log
        Explains how to modify a change log associated with a table using either the Control System or the CLI.
      - Pausing Data Propagation
        Explains how to pause data propagation using either the Control System or the CLI.
      - Resuming Data Propagation
        Explains how to resume a paused change log using either the Control System or the CLI.
      - Removing Change Logs
        Describes how to remove change logs using either the Control System or the CLI.
    - Troubleshooting Changelogs
  - Indexing HPE Data Fabric Database Binary Tables with Elasticsearch
    As of with MapR 6.0, HPE Data Fabric Database Elastic Search integration capability is deprecated and no longer available in the HPE Data Fabric Database product.
- Administering Streams
- Administering Data Fabric Gateways
  A HPE Data Fabric gateway mediates one-way communication between a source HPE Data Fabric cluster and a destination cluster. You can replicate HPE Data Fabric Database tables (binary and JSON) and HPE Data Fabric Streams streams. HPE Data Fabric gateways also apply updates from JSON tables to their secondary indexes and propagate Change Data Capture (CDC) logs.
- Administering Services
- Monitoring the Cluster
  This section describes how to monitor the health and performance of a MapR cluster.
- Configuring Security
  Describes how to configure security and manage secure clusters.
- Managing Secure Clusters
  Provides procedures that will enable you to use Data Fabric clusters securely.
- Administering the Data Access Gateway
  The HPE Data Fabric Data Access Gateway is a service that acts as a proxy and gateway for translating requests between lightweight client applications and the HPE Data Fabric cluster. This section describes considerations when upgrading the service, how to modify configuration settings, and how to administer and manage the service.
- Planning for High Availability
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Troubleshooting Cluster Administration
  Lists the common errors and their solutions.
- Best Practices for Backing Up HPE Data Fabric Information
