Easy to deploy, cost-effective, and integrates seamlessly with other products
We had planned for an RDBMS version and not NoSQL. We use MariaDB Galera Cluster. It's a good product. It is cheap, scalable, performs well, and is efficient. We use GCP’s BigQuery for machine learning. We must follow the best practices of the tool. We missed some best practices like the storage engine and InnoDB. It was very difficult to identify why we were having performance issues. Then, we realized that some of our tables were still on MyISAM, the default storage engine. When we switched it back to the InnoDB, it was very smooth. InnoDB is the recommended one. We must follow the best practices given in the documentation during the initial setup. Overall, I rate the product a nine out of ten.

Cons

"The solution should have a more user-friendly user interface."
"A well-known issue for a lot of different users is associated with write-intensive applications."
"MariaDB can improve by adding more features. There are a lot of features, which are available in Oracle, and which are not available in MariaDB. We hope they will introduce the features soon."
"The interface should be more user-friendly. It should be able to connect directly to the database and Interact with it without having to use commands. It needs better integration."
"While MariaDB is a good relational database, it can be inflexible for complex use cases."
"An improvement would be scaling it up to the levels of Oracle, especially when it comes to resilience, so that we can do higher transactions for two databases or power our operation."
"The GUI could be improved a bit. The user interface needs to be improved."
"Document caching is an area of concern in the product, where improvements are required to help MariaDB improve on the previous queries as they are retained, and you can roll back to them."
"MariaDB's GUI is an area with certain shortcomings where improvements are required."
 

Pricing and Cost Advice
