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…

Has supported web application data needs but requires design adjustments to manage complex queries efficiently
Complex queries in MariaDB where the query needs to parse thousands of lines or data values face some performance issues. For small and medium-size volume, it is pretty good. If it goes beyond certain data and complex queries, we see performance issues. We tried the advanced replication feature between different regions, replicating data specifically residing on MariaDB to two different regions of MariaDB data, and there were some technical snags in terms of slowness and longer processing time. Point-in-time recovery in MariaDB is good for small databases. When data volume increases beyond 5 GB or 10 GB per day or runs into double-digit GBs, we found some performance issues. For data below 10 GB, it works fine. Performance is the primary focus area for MariaDB, particularly during transactions or complex query jobs where slow performance is observed. MariaDB is scalable and easy to scale.

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+."
"Configuration, setup, and schema design are good features in MariaDB, and typical database features we have used include backup, configuration, recovery, archiving, and ETL."
"The most valuable feature of the solution is the query speed it offers."
"They provide a high level of technical support."
"The speed and functionality are the most valuable features."
"If they want an open-source database that can handle huge volumes and is reliable and strong, then I would recommend it."
"A valuable feature is that we can use it for quite a few things, all the things you'd expect from a server—along the lines of Linux's Lightweight Directory."
"What I like best about MariaDB is that it is open-source and reliable."
"Great monitoring and performance stability."
 

Cons

"The solution should have a more user-friendly user interface."
"Lacks time series data and additional driving support would be helpful."
"The features available are very basic."
"The GUI could be improved a bit. The user interface needs to be improved."
"It requires enterprise integration improvements from the security, and audit perspective (AD integration etc.). Also, existing integration into BI tools is not present."
"It would be helpful if I could specify multiple drives for the database storage."
"Could have more integration with user platforms."
"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."
"The difficult part related to the product stems not from the tool itself but is related to learning how to implement the product in the right way without creating any wrong configuration that could cause security issues or performance issues."
 

Pricing and Cost Advice

Information not available
"It's an open-source solution."
"We use the solution's free version."

"The price could be less expensive."
"This is an open source solution with no licensing fees."
"When it comes to MariaDB, it should have a more cost-effective license."
