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+."
"The product has been stable and reliable."
"We like the easy way that we can collect data from other databases."
"It is a scalable solution. It easily scales up and scales down."
"The documentation is quite straightforward."
"If they want an open-source database that can handle huge volumes and is reliable and strong, then I would recommend it."
"We have been running our instance since 2013 and it needs almost no maintenance."
"What I like is that it's very easy to configure, and just from time to time, you can make your backups, and that's it."
"MariaDB is very stable."
 

Cons

"The solution should have a more user-friendly user interface."
"One feedback I can quickly provide is the need for a robust IDE for MongoDB. The existing PHP admin console doesn't meet the client's requirements effectively."
"It's not very stable. It needs improvement."
"The price could be less expensive."
"The dashboard and pricing need improvement."
"A well-known issue for a lot of different users is associated with write-intensive applications."
"The solution can improve by having support for more integration. However, at this time it is working well for us."
"I would like to see a better user interface which would make the tool less complex."
"The PL/SQL performance is slow. If you have big batch jobs running in the middle of the night for a bank doing its end-of-day audits, then MariaDB will take three times longer than using Oracle."
