  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.
- Administering Streams
  - Managing Streams
    This topic provides information about managing streams in HPE Data Fabric Streams.
  - Managing Topics
    Topics are logical collections of messages. The following sections describe how to create and manage topics.
  - Managing Stream Replication
    This section contains topics about setting up stream replication and administering existing replicas.
    - Preparing Clusters for Stream Replication
      Configuring clusters for participation in the replication of HPE Data Fabric Streams streams involves configuring two or more gateways on destination clusters and, if the clusters are secure, setting up secure communications between the clusters.
    - Adding Stream Replicas
      You can create stream replicas using the Control System and the CLI. When you add a replica using the Control System, you can also set up and start replication between a source and replica stream.
    - Setting Up Stream Replication Using the CLI
      Describes how to run the maprcli stream replica autosetup command to set up primary-secondary or multi-master replication from an existing source stream.
    - Viewing the List of Stream Replicas
      Explains how to view the list of replicas for a stream using the Control System and the CLI.
    - Editing a Stream Replica
      Explains how to edit a stream replica using the Control System and the CLI to modify the way in which messages are replicated from the source stream to the replica.
    - Removing Stream Replicas
      Explains how to unregister one or more replicas using the Control System and the CLI.
    - Pausing Stream Replication
      Explains how to pause replication from a source stream to a replica stream using the Control System and the CLI.
    - Resuming Stream Replication
      Explains how to resume replication from one stream to another stream using either the Control System or the CLI.
    - Managing Upstream Sources for Stream Replicas
      - Set up Stream as Upstream Source
        Describes how to set up the current stream as the upstream source for a replica if the replica was not set up to automatically resync with the current stream.
      - Adding Upstream Source for a Stream
        Explains how to add an upstream source for a stream using either the Control Panel or the CLI.
      - Listing all Upstream Sources for a Stream
        Describes how to list all the upstream sources for a stream using the Control System and the CLI.
      - Removing Upstream Sources for a Stream
        Explains how to un-register a stream as an upstream source for a stream using either the Control System or the CLI.
  - Preparing Clusters for Log Compaction
    Describes how to prepare your environment so you can use log compaction.
  - Mirroring Topics with Apache Kafka MirrorMaker
    Use the Apache Kafka MirrorMaker utility either to mirror topics that are in Apache Kafka clusters to streams that are in HPE Data Fabric clusters or to Mirror topics that are in HPE Data Fabric clusters to Apache Kafka clusters.
  - Mirroring Topics with HPE Data Fabric MirrorMaker 2
    MirrorMaker 2.0 is a multi-cluster, cross-data-center replication engine based on the Kafka Connect framework. MirrorMaker 2 is available starting in EEP 8.0.0.
- 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
  Lists the best practices and performance considerations to follow when backing up HPE Data Fabric information.
- IPv6 Support in Data Fabric
  Describes the IPv6 support feature for Data Fabric.
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.

Set up Stream as Upstream Source

Describes how to set up the current stream as the upstream source for a replica if the replica was not set up to automatically resync with the current stream.

Setting Up Current Stream as Upstream Source for a Replica Using the Control System

About this task

To set up a stream as the upstream source for a replica:

Procedure

Go to the Replication tab in the stream information page
Select the checkbox beside the replica(s) that do not have the current stream configured as upstream source for automatic resync.
Selecting a checkbox next to a replica makes the Actions drop-down menu available.
Select Set Current Stream as Upstream Source from the Actions drop-down menu.
The Set Current Stream as Upstream Source dialog displays.
Review the list of selected replicas and click Set Upstream Source.
The current stream will automatically send updates to the replica(s).

Setting Up Stream as Upstream Source for a Replica Using the CLI or REST API

About this task

The basic command to set a table as the upstream souce for a replica is:

maprcli stream upstream add -path <replica stream path> -upstream <source stream path>

See stream upstream add for complete reference information.
