- Configuring and Managing MapR Gateways
  A MapR gateway mediates one-way communication between a source MapR cluster and a destination cluster. MapR-DB tables and MapR Streams streams can be replicated.
- Administering MapR-DB
  Administration of the MapR-DB is done primarily via the commmand line (maprcli) or with the MapR Control System (MCS). Regardless of whether the MapR-DB table is used for binary files or JSON documents, the same types of commands are used with slightly different parameter options. MapR-DB administration is associated with tables, columns and column families, and table regions.
- Configuring Security
  Describes tasks for configuring MapR security, managing secure clusters, and administering auditing.
- Administrator's Reference
  This section contains in-depth reference information for the administrator.
- Glossary
  This section contains defintions for commonly used terms in MapR Converged Data Platform environments.
