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

"Postgres has some functions called JSONB aggregators or other aggregators, which are quite useful."
"Initial setup is simple."
"The database has excellent performance."
"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 solution has many valuable features such as it easy to use and the interface is intuitive."
"The performance is good."
"The solution is quite stable."
"This is an open-source solution, operates at a high speed, and supports more than one SQL language."
"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 performance of Redis is very fast."
"I use Redis mostly to cache repeated data that is required."
"The product offers fast access to my database."
"Redis is a simple, powerful, and fast solution."
"The online interface is very fast and easy to use."
"The solution is fast, provides good performance, and is not too expensive."
"It makes operations more efficient. The information processing is very fast, and very responsive. It's all about the technology."
 

Cons

"The pricing could be better."
"We often find the solution's datetime datatype challenging."
"As PostgreSQL is an open-source product, you do have to do a bit more configuration and management yourself."
"I had some issues when I integrated with the Jupyter Notebook."
"I don't think PostgreSQL supports bulk databases, so it needs to have more capabilities in terms of managing the bulk data."
"It is possible that in the newer version this has been addressed, but I would like the deployment in microservices architecture could be improved."
"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."
"The solution needs to improve the query, documentation, and JSON data functionality."
"The initial setup of Redis was difficult, with a rating of two or three out of ten."
"The development of clusters could improve. Additionally, it would be helpful if it was integrated with Amazon AWS or Google Cloud."
"The only thing is the lack of a GUI application. There was a time when we needed to resolve an issue in production. If we had a GUI, it would have been easier."
"Sometimes, we use Redis as a cluster, and the clusters can sometimes suffer some issues and bring some downtime to your application."
"There are some features from MongoDB that I would like to see included in Redis to enhance its overall efficiency, such as the ability to perform remote behaviour. MongoDB is more efficient in handling updates than deletions and is quicker in processing updates, but it can be slower regarding deletions. This can sometimes pose a challenge, especially when dealing with large datasets or frequent data manipulations that involve deletions. In such cases, I often rewrite columns or update values instead of directly deleting data, as it can be more efficient."
"Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."
"It's actually quite expensive."
"Redis should have an option to operate without Docker on a local PC."
 

Pricing and Cost Advice

"It is also open-source so it is free."
"There is an annual license."
"PostgreSQL is open-source, so if capable admins are available then the setup cost can be $0."
"The licensing model is good."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"This solution can offer a cheaper choice for customers since it is open-source."
"Our company pays for it. There are free versions available, but for advanced features, you obviously have to pay."
"Affordable solution."
"Redis is an open-source solution. There are not any hidden fees."
"Redis is not an overpriced solution."
"Redis is an open-source product."
"We saw an ROI. It made the processing of our transactions faster."
"The tool is open-source. There are no additional costs."
