An easy-to-deploy solution that can be used for data ingestion and usage

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.

"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."
 

Cons

"The scaling for database online transactions needs improvement."
"MariaDB doesn't handle long or complex SQL queries quite as well as Oracle Database."
"I would like to see more compatibility going forward. This would help if there is a need to change databases."

"I would like to see a better user interface which would make the tool less complex."
"The maintenance and performance could be a bit better."

Pricing and Cost Advice

Information not available
"It's an open-source solution."
"MariaDB is an open-source software, meaning I don't need to pay for the product."
