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.

Real-time analytics have transformed response times and support huge data volumes with compression
I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.

Quotes from Members

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

Pros

"The solution is competitive with Mongo, MySQL, and maybe even Oracle."
"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."
"It efficiently handles low-code data and supports read-and-write operations for clustering."
"Security is the most valuable feature."
"The most valuable aspects of this solution are the fast caching and improved performance to the database."
"The scalability of the solution is very good, and it's able to support large amounts of data once the architecture is in place."
"The solution's most valuable feature is its performance optimization within our hardware environment."
"The solution provides a good environment and it's a product we trust."
"The solution is very fast."
"I find the performance features of Oracle Database In-Memory to be most beneficial."
 

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."
"More features in monitoring and the reporting could make it better."
"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."
"Lacks sufficient integration with other tools."
"The high cost of the product is an area of concern where improvements are required."
"It's good and it functions, but it's not the easiest add-on to Database to work with."
"They should lower the price. My customers think that it's too expensive."
"Oracle Database In-Memory appliance-based solutions can be restrictive for some applications, as they may require more flexibility in the database design to be tuned and sized to the customer's needs."
"The product could benefit from enhancements in its graphical user interface."
"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."
"We use some partitions in In-Memory. We have a very large table and a low dose. It is very expensive in data to load all of them into In-Memory. It takes up more memory slots in the server, as well as a lot of RAM. We use last partitions on the table. We always need to create a script and make a schedule that can load a last partition in In-Memory. Oracle doesn't have features to do this automatically. I would like them to allow us to load last partitions, as well as other table partitions, in In-Memory. I think a good feature would do that automatically, letting you see a table, load a large partition, and monitor loading memory. It's quite a good feature."
 

Pricing and Cost Advice

"Citus Data is an open-source product."
"The product is expensive."
"Database In-Memory is priced a bit higher than its competitors like Microsoft."
"The platform's licensing cost needs improvement."
"The solution's pricing is high."
"It's quite costly and it comes with a fixed price."
"I rate the pricing a zero out of ten because Database In-Memory is too costly."
"Oracle Database In-Memory is expensive."
"The pricing is pretty good so I rate it an eight out of ten."
