Find out what your peers are saying about Microsoft, Oracle, SAP and others in Relational Databases Tools."Performance is a top priority, and it excels in this aspect."
"We mainly chose Exasol for its performance reasons."
"The most valuable feature of Exasol is its speed."
"The speed is very good compared to other databases, like SQL Server or Oracle."
"We can quickly scale the solution as it works on an MPP system."
"It is easy to scale."
"The solution is hands-off; you set it up insert your data and it self tunes queries."
"Its speed is great."
"We are able to execute very complex queries. Over 90 percent of our query executions are one second or less. We do millions of queries everyday."
"IBM Netezza Performance Server is a cost-effective solution."
"The data governance prospect... from what I've seen, that is a really powerful tool as well, to help with data lineage and keeping track of that."
"The benefit is really because of the additional speed that we have and, truth be told, the more updated ETL processes and the revamped scheduler in general."
"The most valuable feature would be the fact that it has been running for awhile in an appliance format."
"The performance is most important to me, and it helps our ability to make business decisions quickly."
"The underlying hardware that IBM provides with this appliance is made for a specific purpose, to serve performance on a large amount of data, and to do analytics as well. It is faster, when you compare it to any other product."
"Distribution concurrency control."
"You have to install Exasol drivers, and it's not easy to find or implement a driver into different systems."
"It's not cloud-native so many maintenance operations require downtime."
"Lacks a cloud-based platform."
"They don't talk very well to with other products when it comes to connectivity. Integration is lacking."
"They should improve the security features for MPP processing."
"There are limited resources available to help me resolve the issue with Exasol."
"The only area where we found it could improve was in custom role creation and security, and it was difficult to work with."
"It would be beneficial if the updates would occur more often."
"Concurrency limit needs to be increased somewhat."
"Our main problem with it is concurrency. When there are too many users running Netezza at the same time, this is when we have the most complaints."
"The only issue is that it's not expandable."
"LIke Teradata, we can’t add a node/SPU to the existing appliance."
"The scalability is not as expected. The capacity in the black box is not enough."
"IBM Netezza Performance Server could improve its interface, support for big data, and APA-based connectivity should be available."
"We are not able to scale. The only way to scale is to get another appliance, but we have a customers who would need us to hydrate the data between the two appliances, and Netezza does not do that."
"Oracle Exadata's security features, like TDE encryption, are missing in IBM Netezza Performance Server."
