Enhancing analytics with seamless data dumping and reliable support
Our primary use case is data storage and analytics The organization has decided to purchase a full stack solution from IBM due to positive responses, which helped them upgrade from the previous version. The data dumping into the raw zone and the feature of BigQuery is quite attractive. There…

The limitation we encountered was related to speed, prompting us to increase our AWS cloud thresholds and benchmarks on the servers, adding more throughput. We have been testing that, but speed remains one of our key issues. The integration has been awesome because of the platforms and their usage, and usability is great. The most challenging aspect is finding Teradata resources, so we are focusing on internal training and looking for more Teradata experts. If Teradata could provide a list of certified experts, that would be fantastic. I rated Teradata a nine because the main area for improvement is the bandwidth of resources that could assist us in applying to our projects, specifically more certified and expert resources. The market share of Teradata professionals is limited, creating an issue for us.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
"The performance is okay as long as the volume of queries is not too high."
"It is stable when there is support from IBM."
"It will be MPP, so performance should improve."
"The most valuable features are the Shared-nothing architecture and data protection functionality."
"It is very stable. It's 100% uptime. Speed and resilience are one of the greatest features of this product. In almost twenty years we've never had downtime, except for outages for patches and upgrades. We've never had a system failure in twenty years."
"​Parallel processing features have helped to easily dump any size of data and retrieve data with great performance."
"The flexibility in design is very good."
"The product's scalability is great. Scalability-wise, I rate the solution a ten out of ten."
"IntelliFlex is easy to scale - one of its best features is that you can upscale it to the size you want."
"Teradata effectively uses parallelism to the granular level, performing better than other databases."
"The most valuable features are the large volume of data and the structuring of the data to optimize it and get very optimal data warehouse solutions for customers."
 

Cons

"Right now, we are implementing on ESX VMware 6.0. Support for this platform is poor. Also, one of the backup/recovery options is broken and IBM is not addressing the issue."
"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
"Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"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."
"It needs a teaching web site with more training on third-party tools used for BI."
"Stability-wise, we have had some issues with automation and the ability to handle large datasets."
"I would like to see more integration with many different types of data."
"The cloud is the new challenge and the new opportunity."
"Teradata has a few AI models, but in data science, we need more flexibility."
"The capability to implement it with comparable performance across various private cloud environments, ensuring adaptability to different infrastructure setups would be beneficial."
"​The initial setup was complex as we had to rewrite a lot of the code.​"
 

Pricing and Cost Advice

"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
"The price of Teradata could be less expensive."
"Users have to pay a yearly licensing fee for Teradata IntelliFlex, which is very expensive."
"I am using the free version of Teradata."
"Teradata's licensing is on the expensive side."
"The price of Teradata is on the higher side, and I think that it where they lose out on some of their business."
"The price needs to be more competitive as Hadoop, Redshift, Snowflake, etc are constantly making way into EDW space."
"The cost of running Teradata is quite high, but you get a good return on investment."
"Teradata is a very expensive solution."
