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.

Very scalable with high availability and excellent technical support

The good thing is that there are improvements coming with later function levels for the z/OS Db2. I'd like it if, with the operating system that we've got, z/OS, on the mainframe, it would allow us to refresh the hardware to run Linux dockers on the mainframe. This means this might give us opportunities for different ways of coming into the Db2 environment in the future. We just want a bit more integration with Linux. That said, we are already seeing Linux more readily available on the mainframe environment. Not only have we got the premium operating systems on OS. We can run LPARs on the same mainframe footprint that is also supporting Linux. This is what has improved and made the mainframe environment more competitive. We're also looking at AI for Db2 as well, and machine learning for the future. We know that AI has come out, that we're going to get that, and we're going to evaluate that product next year for Db2. That said, I haven't got any real complaints about Db2 on the mainframe. For the most part, a lot of the problems we have nowadays are to do with communication between the various teams that you would class as stakeholders.

Quotes from Members

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

Pros

"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."

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

"The most valuable features of this solution are security and stability."

"The self-management and optimization features are probably the best on the market"

"The initial setup was easy."

"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."

"Db2's best features are that it's self-maintaining and self-monitoring, which means I have to view and monitor the database far less often."

"The solution's initial setup is straightforward."

"Very good for performance and scalability."

"I can easily export that to further work on it in Snowflake."

Cons

"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's data retrieval speed could be improved, especially for heavy queries. Better optimization or indexing might also be involved."

"Its process of building up queries could be more accessible."

"There are some issues with Db2's database file system not being readable. The storage could also be increased, and the monitoring could be improved."

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

"The pricing could be improved, it's expensive."

"The usage of Db2 could be simplified, as it is quite complex and requires substantial knowledge of Db2 and zOS."

"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."

"The initial setup could be improved."
