We performed a comparison between IBM Netezza Performance Server, Teradata, and VMware Tanzu Greenplum based on real PeerSpot user reviews.
Find out what your peers are saying about Snowflake Computing, Oracle, Teradata and others in Data Warehouse."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 most valuable feature would be the fact that it has been running for awhile in an appliance format."
"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."
"Distribution concurrency control."
"IBM Netezza Performance Server is a cost-effective solution."
"The performance is most important to me, and it helps our ability to make business decisions quickly."
"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."
"We really enjoy the FastLoad, TPump, and MultiLoad features."
"Cuts time to process huge amounts of data with efficient analytical queries."
"Teradata can be easily used in ETL mode transformations, so there is no need for expensive and inconvenient ETL tools"
"The key advantages are Performance when processing Terabytes of data and scalability."
"It's a pre-configured appliance that requires very little in terms of setting-up."
"Teradata's best feature is its speed with historical data."
"The ability to handle machine data parallel processing is the most valuable feature of Teradata."
"It effectively has allowed us to remove over 20 portion copies of the data sets on other DB platforms for real-time operational reporting purposes."
"With VMware Tanzu Greenplum, one can make a huge database table and analyze the queries by adding in the SQL command. Some hint or command for the query goes over the multi-parallel execution."
"Helps us to achieve large-scale analytics."
"We chose Greenplum because of the architecture in terms of clustering databases and being able to have, or at least utilize the resources that are sitting on a database."
"It's super easy to deploy and it also supports different languages and analytics."
"The loading speed is very good."
"Scalability is simple because it's an MPP database. If you need more processing power or you need more storage, you just add a few more nodes in the cluster. It works on common commodity hardware. You can use any type of server. You don't need to have proprietary hardware. It's fairly flexible."
"The most valuable feature for us is horizontal scaling."
"Very fast for query processing."
"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."
"The scalability is not as expected. The capacity in the black box is not enough."
"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."
"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."
"IBM Netezza Performance Server could improve its interface, support for big data, and APA-based connectivity should be available."
"The only issue is that it's not expandable."
"LIke Teradata, we can’t add a node/SPU to the existing appliance."
"Oracle Exadata's security features, like TDE encryption, are missing in IBM Netezza Performance Server."
"The user interface needs to be improved."
"Teradata's UI could be improved."
"GUI of administrative tools is really outdated."
"Limited interest and success in some areas make us hesitate about upgrading."
"Teradata needs to expand the kind of training that's available to customers. Teradata only offers training directly and doesn't delegate to any third-party companies. As a result, it's harder to find people trained on Teradata in our market relative to Oracle."
"It needs a teaching web site with more training on third-party tools used for BI."
"Teradata is an old data warehouse, and they're not improving in terms of new, innovative features."
"I'm not sure about the unstructured data management capabilities. It could be improved."
"We would like to see Greenplum maintain a closer relationship with and parity to features implemented in PostgreSQL."
"Tanzu Greenplum's compression for GPText could be made more efficient."
"One of the disadvantages, not a disadvantage with the product itself, but overall, is the expertise in the marketplace. It's not easy to find a Greenplum administrator in the market, compared to other products such as Oracle."
"The installation is difficult and should be made easier."
"Initial setup is a little complex. It took around two weeks to deploy."
"Lacks sufficient inbuilt machine-learning functions for complex use cases."
"It will be very useful if we could communicate with other database types from Greenplum (using a database link)."
"Implementation takes a long time."
