Overview
This page details step 4 of a 5-step procedure for deploying Single-Node Enterprise ColumnStore 5 with Object storage.
This step tests MariaDB Enterprise Server 10.5 and MariaDB Enterprise ColumnStore 5.
Interactive commands are detailed. Alternatively, the described operations can be performed using automation.
Test S3 Connection
MariaDB Enterprise ColumnStore 5 includes a testS3Connection
command to test the S3 configuration, permissions, and connectivity.
On each Enterprise ColumnStore node, test the S3 configuration:
$ sudo testS3Connection
StorageManager[26887]: Using the config file found at /etc/columnstore/storagemanager.cnf
StorageManager[26887]: S3Storage: S3 connectivity & permissions are OK
S3 Storage Manager Configuration OK
If the testS3Connection
command does not return OK
, investigate the S3 configuration.
Test Local Connection
Connect to the server using MariaDB Client using the root@localhost
user account:
$ sudo mariadb

Test ColumnStore Plugin Status
Query information_ACTIVE
:
SELECT PLUGIN_NAME, PLUGIN_STATUS
FROM information_schema.PLUGINS
WHERE PLUGIN_LIBRARY LIKE 'ha_columnstore%';
+---------------------+---------------+
| PLUGIN_NAME | PLUGIN_STATUS |
+---------------------+---------------+
| Columnstore | ACTIVE |
| COLUMNSTORE_COLUMNS | ACTIVE |
| COLUMNSTORE_TABLES | ACTIVE |
| COLUMNSTORE_FILES | ACTIVE |
| COLUMNSTORE_EXTENTS | ACTIVE |
+---------------------+---------------+
Test ColumnStore Table Creation
Create a test database, if it does not exist:
CREATE DATABASE IF NOT EXISTS test;
Create a ColumnStore table:
CREATE TABLE IF NOT EXISTS test.contacts ( first_name VARCHAR(50), last_name VARCHAR(50), email VARCHAR(100) ) ENGINE=ColumnStore;
Add sample data into the table:
INSERT INTO test.contacts (first_name, last_name, email) VALUES ("Kai", "Devi", "kai.devi@example.com"), ("Lee", "Wang", "lee.wang@example.com");
Read data from table:
SELECT * FROM test.contacts;
+------------+-----------+----------------------+ | first_name | last_name | email | +------------+-----------+----------------------+ | Kai | Devi | kai.devi@example.com | | Lee | Wang | lee.wang@example.com | +------------+-----------+----------------------+
Test Cross Engine Join
Create an InnoDB table:
CREATE TABLE test.addresses ( email VARCHAR(100), street_address VARCHAR(255), city VARCHAR(100), state_code VARCHAR(2) ) ENGINE = InnoDB;
Add data to the table:
INSERT INTO test.addresses (email, street_address, city, state_code) VALUES ("kai.devi@example.com", "1660 Amphibious Blvd.", "Redwood City", "CA"), ("lee.wang@example.com", "32620 Little Blvd", "Redwood City", "CA");
Perform a cross-engine join:
SELECT name AS "Name", addr AS "Address" FROM (SELECT CONCAT(first_name, " ", last_name) AS name, email FROM test.contacts) AS contacts INNER JOIN (SELECT CONCAT(street_address, ", ", city, ", ", state_code) AS addr, email FROM test.addresses) AS addr WHERE contacts.email = addr.email;
+----------+-----------------------------------------+ | Name | Address | +----------+-----------------------------------------+ | Kai Devi | 1660 Amphibious Blvd., Redwood City, CA | | Lee Wang | 32620 Little Blvd, Redwood City, CA | +----------+-----------------------------------------+ +-------------------+-------------------------------------+ | Name | Address | +-------------------+-------------------------------------+ | Walker Percy | 500 Thomas More Dr., Covington, LA | | Flannery O'Connor | 300 Tarwater Rd., Milledgeville, GA | +-------------------+-------------------------------------+
