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.
