PavithrarajShetty - PeerSpot reviewer
Offers simplicity and is cheaply priced
I haven't gone through the scalability aspect since I was using MySQL Server. I haven't worked to a high level in PostgreSQL, but with MySQL Server, I have managed clustering and partitioning. I think I haven't put much focus on PostgreSQL, so I am not sure how it behaves or how it works.
Yaseer Arafat - PeerSpot reviewer
Unmatched Performance and Scalability for Modern Applications
Redis has room for improvement in a few areas. Enhanced tools for managing and monitoring clusters would be beneficial, as would built-in security mechanisms like advanced encryption and granular access controls. Simplifying setup and configuration could make Redis more accessible to new users. Introducing more enterprise-grade features, such as better multi-tenancy support and improved backup and restore capabilities, would also be advantageous. For the next release, it would be great to see enhanced cluster management tools, native multi-region supports for better data redundancy, integrated analytics for deeper insights, AI and ML integration features, and improved developer experience through enhanced SDKs and tools.

Quotes from Members

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

Pros

"We are able to create many different types of jobs and items with this solution making it one of the most valuable features."
"The solution is open-source and free to use."
"The solution has many valuable features such as it easy to use and the interface is intuitive."
"It's a useful solution, that can be widely used."
"PostgreSQL makes it very adaptable to several descriptions of a record. Instead of having several tables or several relations for one entity, I can adapt this entity. It can be a multiform entity. For example, here in Mexico, a company and a person can be sold to us as a physical entity or a physical person."
"The most valuable feature is the performance."
"It is easy to use."
"The product is very similar to the SQL Server."
"The solution is fast, provides good performance, and is not too expensive."
"What I like best about Redis is its fast and easy use. It has interesting algorithms like HyperLogLog and provides useful features. It's also good for implementing scalable rate limiting."
"The ability to fetch and save data quickly is valuable."
"It makes operations more efficient. The information processing is very fast, and very responsive. It's all about the technology."
"Redis is better tested and is used by large companies. I haven't found a direct alternative to what Redis offers. Plus, there are a lot of support and learning resources available, which help you use Redis efficiently."
"The solution's technical support team is good...The solution's initial setup process was straightforward."
"Redis is good for distributed caching management."
"The online interface is very fast and easy to use."
 

Cons

"It needs more integration."
"They need to have a better graphical interface. There is a tool called pgAdmin 4 that they use, which is free. It is written in Java, and it is slow. They need to have a better product that is similar to Toad for Oracle, but, of course, it is hard to get something that's really great and free. Other than that, it is great."
"It would be good to have machine learning functionality in this solution, similar to Microsoft SQL Server and other solutions. Machine learning capability for a basic level or a common user would be useful. It can also have good reporting capabilities."
"Instead of the installation agent downloading all the packages for the install, it should allow the user to download the packages separately on their own to do the install."
"There are some products out there that have a slightly different method of implementation for the SQL language. Some of those are slightly better in some areas, and PostgreSQL is slightly better in some areas. I would probably like to match all of those products together. It is just down to the functionality. For example, Oracle has a number of options within SQL that are outside of what you would class as the SQL standard. PostgreSQL misses some of those, but PostgreSQL does other things that are better than what Oracle does. I would like to merge those two products so that there is a certain amount of functionality in a single product."
"The price could be better."
"We have to set up event API, which takes a lot of events from the user."
"When you get a large number of records in a database and start doing various queries, it can adversely impact the performance of the live running systems. That's an area we continue to look at and mean to improve, but it is not only because of PostgreSQL. It is also because of the way the schemas are put together, and certain events are triggered. So, it is because of both parties."
"The development of clusters could improve. Additionally, it would be helpful if it was integrated with Amazon AWS or Google Cloud."
"I would prefer it if there was more information available about Redis. That would make it easier for new beginners. Currently, there is a lack of resources."
"For the PubSub feature, we had to create our own tools to monitor the events."
"If we use a lot of data, it will eventually cost us a lot."
"Redis presents a single point of failure and lacks fault tolerance."
"The initial setup of Redis was difficult, with a rating of two or three out of ten."
"The tool should improve by increasing its size limits and handling dynamic data better. We use the client ID or associate it with a key for static content. The solution will not be easy for a beginner. Unless you understand SQL data, it will be difficult to understand and use Redis. It also needs to be user-friendly."
"It's actually quite expensive."
 

Pricing and Cost Advice

"The tool is cheaply priced compared to other RDBMS providers in the market."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"It is also open-source so it is free."
"We do not pay for licensing."
"The need for our customers to pay for licences is contingent on their projects and budgets."
"It is free, but if you need support, you can go for the commercial version called EnterpriseDB. They provide paid support, and they can even do hosting for you if you want standby and support."
"Affordable solution."
"The licensing model is good."
"Redis is not an overpriced solution."
"Redis is an open-source solution. There are not any hidden fees."
"The tool is open-source. There are no additional costs."
"We saw an ROI. It made the processing of our transactions faster."
"Redis is an open-source product."
