mcsadmin Commands in 1.4¶

MariaDB ColumnStore ships with a command-line utility and administrative console called mcsadmin to configure and manage MariaDB ColumnStore deployments.

mcsadmin commands can be run as command-line arguments:

$ sudo mcsadmin getStatus

Alternatively, if you need to execute several commands, you can open the administrative console by running mcsadmin without arguments:

$ sudo mcsadmin
