MariaDB Enterprise ColumnStore is available for production in the cloud on MariaDB SkySQL DBaaS. For additional information, see the MariaDB SkySQL Documentation
MariaDB Enterprise ColumnStore is available for production on-premises deployments. For on-premises deployment instructions, choose a topology and version:
MariaDB Enterprise ColumnStore supports multiple topologies. The options described on this page are representative of basic product capabilities.
MariaDB products can be deployed to form other topologies that leverage advanced product capabilities and combine the capabilities of multiple topologies.
MariaDB Enterprise ColumnStore 5 has the following features:
ES 10.4+, CS 10.5+
OLAP and Hybrid
High Availability (HA)
Main Memory Caching
Online Schema changes
Creating a ColumnStore Table
To create a ColumnStore table, use the CREATE TABLE statement with the
CREATE DATABASE columnstore_db; CREATE TABLE columnstore_db.analytics_test ( id INT, str VARCHAR(50) ) ENGINE = ColumnStore;
Configure the Mandatory Utility User Account
To configure the mandatory utility user account, use the mcsSetConfig command:
$ sudo mcsSetConfig CrossEngineSupport Host 127.0.0.1 $ sudo mcsSetConfig CrossEngineSupport Port 3306 $ sudo mcsSetConfig CrossEngineSupport User cross_engine $ sudo mcsSetConfig CrossEngineSupport Password cross_engine_passwd
How many nodes should my multi-node Enterprise ColumnStore deployment have?
If high availability is required, the MariaDB Enterprise ColumnStore deployment must meet some node count requirements:
It should have 3 or more nodes.
It should have an odd number of nodes.
These criteria help to avoid a split-brain scenario.
See Deployment Requirements for Enterprise ColumnStore for more information.
Is MaxScale a required component of multi-node Enterprise ColumnStore?
If high availability is required, a multi-node Enterprise ColumnStore deployment must have at least one MaxScale instance.
If high availability is required for the MaxScale instance too, a multi-node Enterprise ColumnStore deployment must have more than one MaxScale instance. In that case, the MaxScale instances should also be configured to use cooperative locking.
