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 solution is very easy to implement."
"MariaDB has a straightforward initial setup with easy-to-understand documentation."
"The most valuable feature is that it uses multiple cores, which is better than some of the other databases."
"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."
"MariaDB is stable and the initial setup is straightforward."
"It's easy to set up."
"The solution is very stable. It was originally built under MySQL. It has a similar level of stability."
"It's open source."
 

Cons

"The solution should have a more user-friendly user interface."
"With respect to clustering and the master-slave configuration, sometimes the slave goes out of synch."
"Could have more integration with user platforms."
"The solution is not scalable."
"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."
"It doesn't have the same level of maturity metrics as Postgres."
"MariaDB doesn't handle long or complex SQL queries quite as well as Oracle Database."
"Data continuity could be improved."
"MariaDB can improve by adding more features. There are a lot of features, which are available in Oracle, and which are not available in MariaDB. We hope they will introduce the features soon."
