Overview

MariaDB Enterprise ColumnStore 1.4 includes the MariaDB ColumnStore Administrative Console (mcsadmin), which is a command-line interface that can configure, monitor, and manage MariaDB Enterprise ColumnStore.

Reference material is available for MariaDB Enterprise ColumnStore 1.4.

MariaDB Enterprise ColumnStore 1.4 is included with MariaDB Enterprise Server 10.4.

USAGE

The mcsadmin utility can execute many different commands. There are two primary ways to execute commands using mcsadmin.

mcsadmin can be used to run a command by providing the command name and its parameters as command-line arguments:

$ mcsadmin COMMAND [PARAMETER ...]

Alternatively, you can open the administrative console by running mcsadmin without the command name:

$ mcsadmin

Once the administrative console is opened, it can be used to run a command by providing the command name and its parameters:

mcsadmin> COMMAND [PARAMETER ...]
...
mcsadmin> COMMAND [PARAMETER ...]

DETAILS

The MariaDB ColumnStore Administrative Console (mcsadmin) can configure, monitor, and manage MariaDB Enterprise ColumnStore 1.4. Once Enterprise ColumnStore 1.4 has been deployed, you can invoke the console from any of the UM or PM nodes.
