We performed a comparison between Amazon Redshift and IBM Db2 Warehouse 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."You can copy JSON to the column and have it analyzed using simple functions."
"This service can merge and integrate well with all databases."
"It is quite simple to use and there are no issues with creating the tables."
"The most valuable feature is that the solution is fully embedded in the AWS stack."
"I have primarily used the Redshift Spectrum feature and found it most valuable."
"Redshift allows you to transform different data formats and consolidate them into one Redshift cluster. This means you can transform various siloed data sources like Excel files and CSV files into Redshift."
"I like the cost-benefit ratio, meaning that it is as easy to use as it is powerful and well-performing."
"Redshift COPY command, because much of my work involved helping customers migrate large amounts of data into Redshift."
"Some of the best features are stored procedures, parallelism, and different indexing strategies."
"The analytics engine is not bad at forecasting predictions."
"The standout feature of IBM Db2 Warehouse, which is particularly valuable for large enterprises, is its ability to handle big data."
"It can be mounted on the cloud, which is a huge plus. If the client, for example, starts small with on-premise deployment and then it rapidly needs to grow, we can transfer this to the cloud easily."
"Provides good security and reliability."
"I think it scales really well and as long as you take enough time to learn a little bit about it, it works really well."
"The solution is stable."
"The solution has four maintenance windows so, when it comes to stability, I think it would be better to decrease their number."
"In the next release, a pivot function would be a big help. It could save a lot of time creating a query or process to handle operations."
"It would be useful to have an option where all of the data can be queried at once and then have the result shown."
"Migrating data from other data sources can be challenging when you are working with multibyte character sets."
"The technical support should be better in terms of their knowledge, and they should be more customer-friendly."
"In our experiments, the handling of unstructured data was not very smooth."
"The product must provide new indexes that support special data structures or data types like TEXT."
"For people who struggle with IAM or role-based management, the setup isn't easy."
"The biggest challenge anyone could have with Db2 Warehouse is their references or online resources and documentation. They are very, very, very limited on the web."
"In terms of improvement, IBM Db2 Warehouse should be more scalable."
"The areas of the solution that is needing the most improvement are separating compute from storage, elasticity, which means scaling up and then retracting."
"There were some initial challenges with IBM Db2 Warehouse about eight months ago when I worked in this environment. When I coordinated with IBM support, they mentioned that the memory was insufficient for our needs. Our business environment required significantly more memory than the previous cluster could provide. Consequently, we have worked closely with on-site IBM technical personnel to address this issue."
"Lacks sufficient documentation and particularly in Spanish."
"There should be more material available for training and training should be free."
"The biggest problems we have is when the backup solution is failing or slow and we run out of log space, which has happened probably a couple of times in the last four years."
"IBM Db2 Warehouse needs to improve its interface."
