Most Helpful Review
We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
The performance is most important to me, and it helps our ability to make business decisions quickly.
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 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 would be the fact that it has been running for awhile in an appliance format.
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.
Distribution concurrency control.
It is a stable program.
The most valuable features are the Shared-nothing architecture and data protection functionality.
The feature that we find most valuable is its ability to perform Massive Parallel Processing.
It handles large amounts of information with a linear performance increase, in relation to a HW investment.
It has a solid set of tools and consulting services.
It has massive parallel processing ability to do large amounts of concurrent querying.
It has given our business the ability to gain insights into the data and create data labs for analysis and PoCs.
Cuts time to process huge amounts of data with efficient analytical queries.
The scalability is not as expected. The capacity in the black box is not enough.
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.
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 only issue is that it's not expandable.
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.
Concurrency limit needs to be increased somewhat.
LIke Teradata, we can’t add a node/SPU to the existing appliance.
An additional feature I would you like to see included in the next release, is that it needs to be more cloud-friendly.
The user interface needs to be improved.
I would like to see an improved Knowledge Base on the web.
It needs a teaching web site with more training on third-party tools used for BI.
We tried to use case Teradata for a data warehouse system, but we had some problems in relation to the Teradata system, CDC tools, and source databases. We were unable to transfer data from HPE Integrity mainframe to Teradata.
There is a need to improve performance in high transaction processes, as well as the reporting system.
Query language and its functionality are rather limited, compared to Oracle or even SQL Server. However, it is possible to perform any kind of logic in it (though some workarounds may be required).
Data ingestion is done via external utilities and not by the query language itself. It would be more convenient to have that functionality within its SQL dialect.
Pricing and Cost Advice
The pricing is very expensive. It has a lot CPUs with a lot of components in it. It also has built-in redundancy for resiliency reasons.
Netezza is a costly solution. It does serve a specific purpose but it's costlier than what's available in the market, if you go to the cloud.
The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space.
We are looking for a more flexible cost model for the next version that we use, whether it be cloud or on-premise.
Price is quite high, so if it is really possible to use other solutions (e.g. you do not have strict requirements for performance and huge data volumes), it might be better to look at alternatives from the RDBMS world.
