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

"Initial setup is simple."
"The database has excellent performance."
"It is very simple to manage."
"The initial setup is quick and easy."
"The performance is good."
"PostgreSQL has complete SQL dialects and is useful for writing sophisticated and complex queries. We have experience with Oracle database. My partner is experienced in DDA and he writes sophisticated SQL queries. The solution helps to get the job done in the best possible way. In today’s age, most developers do not have strong SQL knowledge or language command. They find it difficult to write even a SQL statement. These developers write cool queries which perform badly on the database end. As DBAs, we constantly urge the developers not to write bad queries, help them learn more, and write placebo commands."
"The main value is that it is open source, which means it is free. Our organization has the initiative to go to open source to cut down on cost. Oracle costs us $6 million a year right now, which is killing us, and Postgres costs nothing. So, there is a big push to go to Postgres."
"PostgreSQL is very powerful, easy to manage, and has many features."
"Redis is a simple service that does what it promises."
"The performance of Redis is very fast."
"Redis has multiple valuable features such as being a free and reliable open-source tool."
"The most valuable features of Redis are its ease of use and speed. It does not have access to the disc and it is fast."
"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."
"Redis acts as an in-memory search tool that improves the speed of operations."
"Redis is a simple, powerful, and fast solution."
"The product offers fast access to my database."
 

Cons

"The scalability is limited."
"Integration with other platforms could be improved."
"The pricing could be better."
"I find it difficult to get connectors on the tool. For example, .NET has only one free provider in PostgreSQL. I need to pay the provider if I need something more sophisticated features. Other languages like PHP and Java have good community support. We need community support for .NET."
"PostgreSQL doesn't have a feature for temporal SQL, which is useful for gathering versions of data. This feature should be included in PostgreSQL. This feature is available in MariaDB, SQL Server, Oracle Database, and DB2."
"The solution needs to improve the query, documentation, and JSON data functionality."
"The database and applications can become very slow."
"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 initial setup of Redis was difficult, with a rating of two or three out of ten."
"In future releases, I would like Redis to provide its users with an option like schema validation. Currently, the solution lacks to offer such functionality."
"Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."
"Redis presents a single point of failure and lacks fault tolerance."
"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."
"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."
"Redis could be improved by introducing a GUI to display key-value pair database information, as it is currently a CLI tool with no visual representation."
"Sometimes, we use Redis as a cluster, and the clusters can sometimes suffer some issues and bring some downtime to your application."
 

Pricing and Cost Advice

"PostgreSQL is a free and open-source database."
"It is an open-source platform."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"We do not pay for licensing."
"It is free. There is no license on it."
"It is also open-source so it is free."
"Affordable solution."
"It is open-source. If you use it on-premise, it is free. It also has enterprise or commercial versions. If you go for the cloud version, there will be a cost, but it is lower than Oracle or Microsoft."
"Redis is an open-source product."
"The tool is open-source. There are no additional costs."
"Redis is an open-source solution. There are not any hidden fees."
"Redis is not an overpriced solution."
"We saw an ROI. It made the processing of our transactions faster."
