Feed: MariaDB Knowledge Base Article Feed. Author: . Note: Columnstore.xml modifications you manually made are not automatically carried forward on an upgrade. These modifications will need to be incorporated back into .XML once the upgrade has occurred. The previous configuration file will be saved as /usr/local/mariadb/columnstore/etc/Columnstore.xml.rpmsave.

Create a .my.cnf file in the user home directory with 600 file permissions with the following content (updating PASSWORD as appropriate): [mysqladmin] user = root password ... Read More

Feed: Planet MySQL; Author: Vlad Mihalcea; (Last Updated On: August 16, 2018) As I explained in this article, multitenancy is an architectural pattern which allows you to isolate customers even if they are using the same hardware or software components. There are multiple ways you can achieve multitenancy, and in this article, we are going to see how you can implement a multitenancy architecture using the database catalog as the unit of isolation. Catalog-based multitenancy can be achieved using any relational database system. However, since MySQL is one of the most popular RDBMS and because it does drive a distinction ... Read More
