MariaDB Enterprise Server Components

Component

Description

MariaDB Enterprise ColumnStore 23.10

  • Columnar Storage Engine

  • Optimized for Online Analytical Processing (OLAP) workloads

Topology

Single-Node Enterprise ColumnStore Topology

The Single-Node Enterprise ColumnStore topology provides support for Online Analytical Processing (OLAP) workloads to MariaDB Enterprise Server.

The Enterprise ColumnStore node:

  • Receives queries from the application

  • Executes queries

  • Uses the local disk for storage.

High Availability

Single-Node Enterprise ColumnStore does not provide high availability (HA) for Online Analytical Processing (OLAP). If you would like to deploy Enterprise ColumnStore with high availability, see Enterprise ColumnStore 23.10 with Shared Local storage.

Requirements

These requirements are for the Single-Node Enterprise ColumnStore, when deployed with MariaDB Enterprise Server 10.6 and MariaDB Enterprise ColumnStore 23.10.

Operating System

  • CentOS Linux 7 (x86_64)

  • Debian 11 (x86_64, ARM64)

  • Debian 12 (x86_64, ARM64)

  • Red Hat Enterprise Linux 7 (x86_64)

  • Red Hat Enterprise Linux 8 (x86_64, ARM64)

  • Red Hat Enterprise Linux 9 (x86_64, ARM64)

  • Rocky Linux 8 (x86_64, ARM64)

  • Rocky Linux 9 (x86_64, ARM64)

  • Ubuntu 20.04 LTS (x86_64, ARM64)

  • Ubuntu 22.04 LTS (x86_64, ARM64)

Minimum Hardware Requirements

MariaDB Enterprise ColumnStore's minimum hardware requirements are not intended for production environments, but the minimum hardware requirements can be appropriate for development and test environments. For production environments, see the recommended hardware requirements instead.

The minimum hardware requirements are:

Component

CPU

Memory

Enterprise ColumnStore node

4+ cores

16+ GB

MariaDB Enterprise ColumnStore will refuse to start if the system has less than 3 GB of memory.

If Enterprise ColumnStore is started on a system with less memory, the following error message will be written to the ColumnStore system log called crit.log:

Apr 30 21:54:35 a1ebc96a2519 PrimProc[1004]: 35.668435 |0|0|0| C 28 CAL0000: Error total memory available is less than 3GB.

And the following error message will be raised to the client:

ERROR 1815 (HY000): Internal error: System is not ready yet. Please try again.

Quick Reference

MariaDB Enterprise Server Configuration Management

Method

Description

Configuration File

Configuration files (such as /etc/my.cnf) can be used to set system-variables and options. The server must be restarted to apply changes made to configuration files.

Command-line

The server can be started with command-line options that set system-variables and options.

SQL

Users can set system-variables that support dynamic changes on-the-fly using the SET statement.

MariaDB Enterprise Server packages are configured to read configuration files from different paths, depending on the operating system. Making custom changes to Enterprise Server default configuration files is not recommended because custom changes may be overwritten by other default configuration files that are loaded later.

To ensure that your custom changes will be read last, create a custom configuration file with the z- prefix in one of the include directories.

Distribution

Example Configuration File Path

  • CentOS

  • Red Hat Enterprise Linux (RHEL)

/etc/my.cnf.d/z-custom-mariadb.cnf

  • Debian

  • Ubuntu

/etc/mysql/mariadb.conf.d/z-custom-mariadb.cnf
