We performed a comparison between Citus Data and IBM Db2 Database based on real PeerSpot user reviews.
Find out in this report how the two Relational Databases Tools solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."You can use Citus Data to write complex scripts. I like its version upgrades and disaster recovery as well."
"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."
"It's very straightforward to implement the solution. It took us two days to set up everything."
"Your iOS, your throughputs, your performance cycles, you cannot touch it with Microsoft or with Oracle scalability-wise. That is far and away the most scalable systems and the highest performing systems of the set of them."
"The most valuable feature of the IBM Db2 Database is the ease of use, and the ability to do query writing of any SQL statement and have an output."
"The stability of IBM Db2 Database is stable. We have not faced any downtime in one year. Our work is mostly during business hours and during that time, we haven't faced any downtime."
"It is quite a stable solution."
"Its robustness, scalability, availability, and performance are valuable. All these are the major attributes of a relational database for supporting a very high-volume business, and Db2 is very good in all those areas and in all those attributes."
"The solution's security is very tough and impenetrable."
"The most valuable features of this solution are security and stability."
"IBM Db2 was much cheaper as a package than using other products. This is because IBM supplied a package with its product. It's an application. So it was much more efficient and a stronger competitor in that regard."
"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."
"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."
"The solution could improve by providing more integration."
"The management of Db2 should be simplified because there are not too many specialists in this area, and the learning curve of Db2 specialists is very long. After the courses, probably it takes one and a half or two years to get to the point when you are using the product properly in the production systems. So, the complexity is very high, and the most important thing is to simplify the management of the product, including self-maintenance. They should simplify the installation, management, and monitoring to simplify the product. It takes too long for a person to be a specialist in this product."
"IBM's products tend to be quite costly, especially given the availability of free, open-source alternatives."
"End-to-end encryption specifically is something the solution needs to have in the next release."
"The only drawback that we see in Db2 Database is the crash recovery. When there is a crash and somebody has to do the recovery, Db2 Database first stops, and then it does any crash recovery. In Oracle Database, crash recovery happens within the database. The database is not shut down."
"The problem with this environment is that any software that you install is very costly because there are no free tools for this environment."
"Also, the website could be more intuitive. I didn't find it easy to find documentation on the website."
"In terms of improvements, IBM Db2 can improve its interface and its functionality. Also, the embedded functions should be much richer than the current ones - the functions which are embedded in the engine itself."
