Featured Reviews

Prabir Kumar Kundu - PeerSpot reviewer
Offers robust security and availability with impressive replication capabilities
Regarding their documentation and interface, there is room for improvement. Documentation is definitely required when running multiple databases on a cluster system. The load balancer, MySQL LB, which is used to connect to the application, lacks clear documentation. When there are multiple application servers connecting to the MySQL cluster and going through the MySQL load balancer, the documentation is not user-friendly. It's there, but only technical persons with deep knowledge of the MySQL database can implement it. Most of the community users or ISVs who use MySQL don't have many technical persons or DBA experts, so they face some challenges for the high availability of connecting high available databases from high available applications. That documentation should be simplified.

Considering that there is a free version of MySQL, would you invest in one of the paid editions?
I may be considered a MySQL veteran since I have been using it since before Oracle bought it and created paid versions. So back in my day, it was all free, it was open-source and the best among sim...
What is one thing you would improve with MySQL?
One thing I would improve related to MySQL is not within the product itself, but with the guides to it. Before, when it was free, everyone was on their own, seeking tutorials and how-to videos onli...
