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 most valuable feature of MariaDB is the replication mode."
"The most valuable feature is that it uses multiple cores, which is better than some of the other databases."
"The most valuable features of the solution stem from the fact that it is a cloud-based tool, so it is pretty fast."
"The initial setup of MariaDB is simple enough."
"MariaDB has a straightforward initial setup with easy-to-understand documentation."
"If you want a reliable, easy to maintain database solution, I think that MariaDB on RedHat/CentOS is an option that every DBA should consider."
"The solution's features have effectively met our operational requirements as a standard SQL database."
"The stability of MariaDB is good, it has high availability."
 

Cons

"The solution should have a more user-friendly user interface."
"MariaDB doesn't handle long or complex SQL queries quite as well as Oracle Database."
"Integration with AWS could be improved."
"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."
"When we have had issues with accidental computer shutdown or a power outage, our MariaDB database was corrupted."
"Master-master replication is something that needs to be simplified."
"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."
"The ability to create stored procedures in MariaDB is an area where the tool lacks a bit."
