Co-Founder at Afriziki

Efficiently handles high-traffic scenarios and compatible with PostgreSQL extensions, offering flexibility in database management

There are many areas of improvement , especially in terms of DDL query routing. Even though it's masterless, DDL queries need to be sent to the coordinator node. Also, setting up a multi-node environment could be more straightforward. Currently, setting up a multi-node environment is challenging. It's a bit tricky. Installation on each PostgreSQL node can lead to communication issues between nodes. An automatic rebalancing feature would be a significant improvement. Currently, I have to manually command the rebalance. It would be more convenient if it was rebalanced automatically. The dashboard and monitoring capabilities are good, but it would be helpful to have an integrated availability dashboard.

Offers optimizer plan and ALSM features along with exceptional stability

The TSA version of IBM Db2 Database doesn't meet my stability expectations. Every time when a switch over occurs, some stability issues can be noticed. The vendor should offer a free version of IBM Db2 Database. For instance, if our company wants to train new individuals on all the features of IBM Db2 Database, they can only be trained after purchasing the paid version of the solution. About ten years ago, a trial version was available for the solution that was highly beneficial for companies. The vendor can add AI or ML features in the future version of IBM Db2 Database.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It's very straightforward to implement the solution. It took us two days to set up everything."

"Its distributed processing capabilities are a standout feature. It requires minimal changes to get up and running if you already have a system on PostgreSQL. Citus can run in its natural state."

"You can use Citus Data to write complex scripts. I like its version upgrades and disaster recovery as well."

"IBM Db2 Database has good performance."

"Db2 database scalability and performance capabilities match our database needs. It covers pretty much everything a database administrator or engineer might need."

"It's very secure."

"Very good for performance and scalability."

"The structure is straightforward, consisting of the test file and the logical and physical files. You have one physical file and many logical files related to it."

"It is a scalable solution."

"Its functionality and availability are valuable. Its availability is great. It is available 99.99% of the time."

"Some of the most valuable features are the scaling from a small very cheap installation to a very large enterprise installation. In addition, the backups and assistance are good."

Cons

"Citus Data needs to improve its stability. Do not consider this product if you have the budget. It is still developing and has a lot of issues."

"More features in monitoring and the reporting could make it better."

"There are many areas of improvement , especially in terms of DDL query routing. Even though it's masterless, DDL queries need to be sent to the coordinator node. Also, setting up a multi-node environment could be more straightforward."

"IBM Db2 Database could improve in the steps it takes for upgrades. It is not an easy process. The process of upgrading the version is lengthy and requires a lot of time. To make it more efficient, I suggest implementing some automation on the solution side. This will greatly reduce the time required for the upgrade."

"The user interface is old and needs to be improved."

"The tool is not easy to use. It needs to improve scale computing so that the tool can be scaled vertically. The product needs to enhance pre-engine optimization and it needs to be more efficient in completing queries. The documentation should be updated to include different scenarios of deployment."

"The GUI interface is not particularly friendly for those who do not have experience with the product."

"I would say that the tool has to be made more cloud-friendly and should have agreements with AWS, Microsoft, or Google to run things on hyperscalers."

"The ease of use, or ease of management, could be improved."

"The data table names are very short which is not user-friendly compared to the Oracle SQL server. It should have longer column and table names."

"The solution no longer supports POWER8."

Pricing and Cost Advice

"Citus Data is an open-source product."

"The solution's pricing is fine."

"Licensing fees are on a yearly basis."

"I rate the product pricing a nine out of ten."

"It's very expensive for West African countries like ours."

"We don't see what the specific price of the DB2 license is because we pay for the backup license as a package."

"They are competitive and honest (compared to how peer firms approach licensing conversations). "

"We did not buy it. It came with our hardware without any complimentary maintenance. If I compare Db2 Database with Oracle Database, its price is lower than Oracle Database."

"If I consider the price of IBM Db2 Database, I would say there are cheaper products in the market."
