Hemanthreddy Vakiti - PeerSpot reviewer
Data engineer at a tech vendor with 10,001+ employees
Optimized restaurant analytics has driven faster insights and streamlined daily reporting
Amazon Redshift offers massive parallel processing capability, allowing it to handle millions of records, along with integration with other AWS features such as S3 and QuickSight. The column-level storage supports high performance and easy data retrieval compared to other tools. The integration with S3 has helped my team immensely since S3 is our starting source, and the direct integration with Amazon Redshift simplifies the transformation and loading process. Columnar storage has benefited our performance significantly, allowing us to extract specific rows from tables with years of data much faster than other tools with row-level storage. Amazon Redshift has positively impacted our organization by significantly improving query performance and speed. Features such as easy integration with S3 allow us to process millions of records efficiently, ultimately saving us nearly one hour per day for our project.

Quotes from Members

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

Pros

"The product is the best database for analytics, BI, and whatever else I encounter."
"Amazon Redshift's performance optimization and scalability are quite helpful, providing functionalities such as scaling up and down."
"It's very easy to migrate from other databases to Redshift. There are migration tools dedicated for this purpose, enabling migration from other databases like MS SQL directly to Redshift. The majority of the scripts will be automatically transposed."
"A feature I find most valuable in Amazon Redshift is that it's fast."
"The most valuable feature is that the solution is fully embedded in the AWS stack."
"The initial setup of this solution is straightforward."
"Redshift's versioning and data security are the two most critical features; when migrating into the cloud, it's vital to secure the data, and the encryption and security are there."
"Fast load times Flexibility in column definitions The ability to reload data multiple times at different times."
"The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger.​"
"Since my company is an IBM partner, it has enabled us to offer cloud data warehouse solutions on a 100% IBM stack."
"I like that the dashDB solution is built on DB2 technology, which means that you can use all the features of a DB2 database while outsourcing all the hardware and software maintenance."
"Ease of migration from Netezza DB; IBM ported over all Netezza's functionality and made the warehouse DB/dashDB the best of breed of the two."
"It will be MPP, so performance should improve."
"DashDB is a good product to work with and the extra cost you spend on performance, technical support and tools to work with is worth it."
"It is stable when there is support from IBM."
"One of the most amazing features of dashDB is how it uses compression to get results in lighting speed."
 

Cons

"We recently moved from the DC2 cluster to the RA3 cluster, which is a different node type and we are finding some issues with the RA3 cluster regarding connection and processing. There is room for improvement in this area. We are in talks with AWS regarding the connection issues."
"The initial setup for Amazon Redshift is often complex. Sometimes they have difficulty understanding what issues we are experiencing."
"Running parallel queries results in poor performance and this needs to be improved."
"There is some missing functionality and sometimes it's so difficult to work in. We need to convert these functionalities using VACUUM inside Amazon Redshift and then it causes some complexity."
"The main issue people complain about, and I agree with the claim, is that it's hard to load your data into it."
"For people who struggle with IAM or role-based management, the setup isn't easy."
"The OLAP slide and dice features need to be improved."
"The product must become a bit more serverless."
"With dashDB, scalability and uptime need more improvement."
"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."
"Db2 is not a solution that I recommend. We have a lot of experience and we are not satisfied with the product or the support that we received."
"There are some limitations in adding data files to table spaces, and improvements are needed for regional support."
"The support channels need to improve."
"I would like to see improvements in backup and authentication. It needs the ability to increase the number of retained backups to more than 2 days."
"I would rate the level of dashDB support 3.5/5. While they are very knowledgeable in many areas, you can still struggle to get the correct resolution."
 

Pricing and Cost Advice

"This solution implements the pay-as-you-use model, so no license. Pricing could be cheaper."
"One of my customers went with Google Big Query over Redshift because it was significantly cheaper for their project."
"The cost must be improved."
"Amazon Redshift is an expensive solution. Larger organizations can afford this solution, but smaller businesses would struggle to afford it."
"Redshift is very cost effective for a cloud based solution if you need to scale it a lot. For smaller data sizes, I would think about using other products."
"The product is quite expensive."
"The solution is available at a mid-range price compared to other vendors."
"At the moment, pricing is a little bit on the higher side, although it depends on the size of the company."
"If your going to go with warehouse DB/dashDB, use the cloud or Sailfish version."
