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

Pros

"The solution returns data quickly, and data retrieval is fast in kdb+."
"The stability of MariaDB is good, it has high availability."
"The most valuable features of the solution stem from the fact that it is an open-source product and offers its users great online community support."
"The product has been stable and reliable."
"MariaDB is scalable."
"The solution's high availability is its most valuable aspect."
"It is a stable solution."
"One of the great features of MariaDB is its scalability. It's easy to handle even with large databases."

Cons

"The solution should have a more user-friendly user interface."
"Master-master replication is something that needs to be simplified."
"In the next release, I would like to see improvements in the scalability and redundancy features."
"The performance could be a bit better."
"The configuration could be improved. It should be easier."
"The stability could always continue to be improved upon."
"I would like to see a better user interface which would make the tool less complex."
"It would be good if they can maybe improve the mass import in the database. Currently, for importing a large number of data, we create a CSV file and upload all the things in the system. The system does not activate them by default. We have to do this manually. This may be due to the version we are using, but this is something we would like to see improved."
"The product needs more features and more functionality. It's imperative that it supports more platforms, and supports more operating systems."

"We use the solution's free version."
"The product is not expensive."
"I rate the product's price a three on a scale of one to ten, where one is low price, and ten is high price since there are some support costs involved, even though it isn't an open-source solution."
"It is free of charge."
"MariaDB is open-source and self-hosted."
