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.
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.
This section describes how to monitor the health and performance of a MapR cluster.
Describes how to configure security and manage secure clusters.
Provides procedures that will enable you to use Data Fabric clusters securely.
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.
This section contains in-depth reference information for the administrator.
This section provides information about the HPE Data Fabric command API. Most commands can be run on the command-line interface (CLI), or by making REST requests programmatically or in a browser.
Each command reference page includes the command syntax, a table that describes the parameters, and examples of command usage.
Verifies given user roles for ACEs exists in the /opt/mapr/conf/m7_permissions_roles_refimpl.conf file.

table
Performs functions related to HPE Data Fabric Database tables.
table create
Creates a HPE Data Fabric Database binary or JSON table.
table cf
Manages column families for HPE Data Fabric Database tables.
These maprcli commands are used to create and manage Change Data Capture (CDC) changelogs. A changelog is used to establish a relationship between a HPE Data Fabric Database source table (JSON or binary) and a HPE Data Fabric Streams stream topic and to manage the propagation process.
