We performed a comparison between IBM Netezza Performance Server and VMware Tanzu Greenplum based on real PeerSpot user reviews.
Find out in this report how the two Data Warehouse solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Distribution concurrency control."
"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."
"The most valuable features of the IBM Netezza Performance Server are the NPS server because of the reduced maintenance and overall good performance."
"IBM Netezza Performance Server is a cost-effective solution."
"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 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 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."
"The most valuable feature for us is horizontal scaling."
"Very fast for query processing."
"Helps us to achieve large-scale analytics."
"It works very well with large database queries."
"Tanzu Greenplum's most valuable features include the integration of modern data science approaches across an MPP platform."
"A very good, open-source platform."
"Scalable (Massive) Parallel Processing (MPP) – The ability to bring to bear large amounts of compute against large data sets with Greenplum and the EMC DCA has proven itself to be very effective."
"Pivotal Greenplum's shared-nothing architecture."
"The only issue is that it's not expandable."
"Oracle Exadata's security features, like TDE encryption, are missing in IBM Netezza Performance Server."
"In terms of features that I would like to see, one is the ability to actually scale out an architecture. Right now, if you buy one, it's fixed. There is no scale-up availability at all."
"LIke Teradata, we can’t add a node/SPU to the existing appliance."
"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."
"Concurrency limit needs to be increased somewhat."
"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."
"IBM Netezza Performance Server could improve its interface, support for big data, and APA-based connectivity should be available."
"The installation is difficult and should be made easier."
"Initial setup is a little complex. It took around two weeks to deploy."
"Tanzu Greenplum's compression for GPText could be made more efficient."
"Some integration with other platforms like design tools, and ETL development tools, that will enable some advanced functionality, like fully down processing, etc."
"Extra filters would be helpful."
"VMware Tanzu Greenplum needs improvement in the memory area and improved methods for quick access to the disc. So, one of the quick goals of Greenplum must work on enhancing access to the disc by adding hints in the database."
"It will be very useful if we could communicate with other database types from Greenplum (using a database link)."
"If you have a user consuming a huge load of resources, it takes down the entire system."
