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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The solution returns data quickly, and data retrieval is fast in kdb+."
"Great monitoring and performance stability."
"The integration with other products is seamless."
"This solution is user-friendly."
"It is a scalable solution. It easily scales up and scales down."
"We like the easy way that we can collect data from other databases."
"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."

"There could be a command-line prompt for repairing the database and fixing indexes, similar to what was available in the old MyISAM storage engine."

"MariaDB could improve by adding support for non-relational structures and new data types."
"A well-known issue for a lot of different users is associated with write-intensive applications."
"I would like to see more compatibility going forward. This would help if there is a need to change databases."
