What's New in MariaDB Enterprise ColumnStore 5.4?

MariaDB Enterprise ColumnStore 5.4 introduces the following new features:

MariaDB Enterprise Server Convergence

MariaDB Enterprise ColumnStore 5.4 converges with MariaDB Enterprise Server even further:

  • It uses a simplified installation procedure, which is similar to other MariaDB Enterprise Server storage engines.

  • It supports even more queries and other features that are supported by MariaDB Enterprise Server.


MariaDB Enterprise ColumnStore 5.4 is included with MariaDB Enterprise Server 10.5:


MariaDB Enterprise ColumnStore 5.4 simplifies the installation process:

  • It is a plugin for MariaDB Enterprise Server.

  • It is deployed by installing a single additional package.

  • Users no longer need to execute columnstore-post-install and postConfigure.

  • It supports running Enterprise ColumnStore as a non-root user.


MariaDB Enterprise ColumnStore 5.4 has been superseded by MariaDB Enterprise ColumnStore 5.5 in MariaDB Enterprise Server 10.5. To install this version, see Deploy MariaDB Enterprise ColumnStore 5.5.


MariaDB Enterprise ColumnStore 5.4 adds support for new clients:


MariaDB Enterprise ColumnStore 5.4 supports simplified administration:

  • mcsadmin has been removed.

  • Enterprise ColumnStore 5.4 uses systemd to administer its service in single-node deployments.

  • It provides a new systemd service called mariadb-columnstore, which is used to manage Enterprise ColumnStore's service in single-node deployments. This systemd service replaces the following mcsadmin commands:

    Old mcsadmin Command

    Replacement systemd Command

    sudo mcsadmin startSystem

    sudo systemctl start mariadb-columnstore

    sudo mcsadmin stopSystem

    sudo systemctl stop mariadb-columnstore

    sudo mcsadmin shutdownSystem

    sudo systemctl stop mariadb-columnstore

    sudo mcsadmin restartSystem

    sudo systemctl restart mariadb-columnstore

    The Enterprise ColumnStore service should not be manually started or enabled in a multi-node deployment. The Enterprise ColumnStore service will be started as-needed by the CMAPI service, so it does not need to start automatically upon reboot.


MariaDB Enterprise ColumnStore 5.4 supports multi-node deployments, which support high availability:


MariaDB Enterprise ColumnStore 5.4 includes CMAPI 1.1, which is a REST API:

  • The REST API provides simplified cluster management for multi-node Enterprise ColumnStore deployments by:

    • Removing the need to configure SSH between nodes in a multi-node Enterprise ColumnStore deployment.

    • Providing an interface for MaxScale 2.5 to orchestrate the multi-node Enterprise ColumnStore deployment.

    • This REST API replaces the following mcsadmin commands for multi-node Enterprise ColumnStore deployments:

    Old mcsadmin Command

    Replacement REST API Command

    sudo mcsadmin getSystemStatus


    sudo mcsadmin startSystem


    sudo mcsadmin shutdownSystem


    sudo mcsadmin addModule


    sudo mcsadmin removeModule


S3-Compatible Object Storage

MariaDB Enterprise ColumnStore 5.4 supports S3-compatible object storage for data:

  • It supports cpimport for multi-node ColumnStore deployments that use S3-compatible object storage.

  • It supports IAM roles.
