Netezza Room for Improvement

It really serves its purpose. It meets the need for performance, it meets the need for robustness, and it also serves as a perfect data warehousing appliance. The only issue is that it's not expandable. The new versions of Netezza, they are expandable. They can be on-prem and on the cloud like dashDB from IBM. It replaces the previous Netezza versions. We are currently on Mako because TwinFin support is going in 2019. Maybe in the next couple of years, we will be replacing Netezza with Redshift. View full review »

Could do better to support more concurrent update queries. We had to stagger our ETL loads to prevent queuing of jobs and random failures. Also, it would have been good if the admin application showed more detail on the validity and usage of zone maps (this may have been implemented in later versions of the admin app).

It is a highly complicated architecture and only IBM engineers/support, or someone who worked on the hardware side of the system, can understand the system architecture completely. This means that: * Replacements can only be done by an IBM engineer * Components are not generic and are not on the market * Many of the systems are IBM patented * Service support costs are high Storage, although high, is limited depending on the rack configuration. For example, an N3001-80, which is an eight-rack Mako Server and also the top end model with the highest storage, can store a maximum of 384TB. Should your data exceed this limit, the storage cannot be extended. It cannot be used for unprocessed data. The data has to be in a table format. View full review »

There won't be another release. They're converting to DB2 and that is one of the reasons we are looking at other options. 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.

Database Admin. Manager at a financial services firm with 1,001-5,000 employees
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. View full review »

Senior Solution Architect at a tech vendor with 1,001-5,000 employees
Marketing, I dare say, should be improved. The ads should never mention “big data” since the platform was not initially designed for it. I worked years and years ago with Teradata, and this is the platform to which it should be compared. It is important to emphasize that Netezza and Teradata have different markets. Netezza performs very well “in its peculiar and valuable small world.” View full review »

They should make it work better in a multi-user context. This solution works, but not for the workload we have. View full review »

This is an appliance-based product with limited capability. It has all the horse-power that one can imagine and can handle all workloads. View full review »
