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+."
"From a customer perspective, MariaDB is a good choice for cluster configuration. It's also easy to operate and cheap."
"One of the great features of MariaDB is its scalability. It's easy to handle even with large databases."
"The technical support of MariaDB is very helpful, and they came and tuned our queries with one-to-one assistance."
"There is the need for a robust IDE for MongoDB. The existing PHP admin console doesn't meet the client's requirements effectively."
"Configuration, setup, and schema design are good features in MariaDB, and typical database features we have used include backup, configuration, recovery, archiving, and ETL."
"I am editing."
"From the user's perspective, the performance of the columnar queries is very good in terms of the database when comparing it to the Oracle, and MySQL."
"The solution's features have effectively met our operational requirements as a standard SQL database."
 

Cons

"The solution should have a more user-friendly user interface."
"The ability to create stored procedures in MariaDB is an area where the tool lacks a bit."
"When we have had issues with accidental computer shutdown or a power outage, our MariaDB database was corrupted."
"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."
"The PL/SQL performance is slow if you have big batch jobs running overnight."
"Could have more integration with user platforms."
"An improvement would be scaling it up to the levels of Oracle, especially when it comes to resilience, so that we can do higher transactions for two databases or power our operation."
"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."
"The solution should do some fine-tuning on maybe the transaction per second so that users can get more than they can on the Microsoft SQL Server."
