An easy-to-deploy solution that can be used for data ingestion and usage
I work for a fintech company where we create several strategies generally built on finance data, which are like one-time series data. We deal with huge bulk data on a daily basis, and we use kdb+ for data ingestion and usage The most valuable feature of kdb+ is the speed at which it returns the…

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+."
"MariaDB is a user-friendly solution. Performance wise, it's better than SQL. With SQL, I would need to write a number of queries. In contrast, MariaDB is light."
"I like the global transaction IDs (GTIDs) feature. It's quite reliable for replication between a master and a replica server, and it's a feature that MySQL also has but implemented differently."
"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."
"It's a very easy product to set up."
"The most valuable feature of MariaDB is that it is open-source and we can easily migrate from other databases, such as Oracle to MariaDB."
"The solution's features have effectively met our operational requirements as a standard SQL database."
"It delivers fast processing times, particularly for frequent select queries and insert/update operations."
"There is the need for a robust IDE for MongoDB. The existing PHP admin console doesn't meet the client's requirements effectively."
 

Cons

"The solution should have a more user-friendly user interface."
"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."
"The only potential area for improvement could be the pricing model, which might benefit from being more flexible or a bit cheaper."
"Lacks time series data and additional driving support would be helpful."
"Maria DB has to improve from a management perspective."
"Master-master replication is something that needs to be simplified."
"MariaDB should provide HA and archive logging... I haven't had the opportunity to use the features provided by the solution since I don't know how to see them."
"Replication could be better, and it's not so simple. It would be better if they had a replication server. It would make things a lot easier. You need to have that replication server, but not in the same server farm. Then there will be a bit of latency between both because you should have one in one city and another one in a different city. That kind of solution should be more baked into every single database today. Mirroring the database in a live environment where any record written on the production server replicates instantly across the fiber on the other server wasn't easy. Many people don't even bother with that, and they just run one server."
"It's not very stable. It needs improvement."
