Transaction processes are fast and good replication capability
Use cases include querying data warehouses and databases to fetch data for clients already working on PostgreSQL.  We also use Postgres for building reports It's a transactional database, so we use Postgres for most of our reporting. That's where it's helping. The query speed is fast, and the…

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

"The most valuable features are the price, stability, it is scalable and is used by our clients in small business environments, and it is a simple product to use."
"Initial setup is simple."
"It has completely met our needs. It works, and it is robust. We haven't had any problems with what PostgreSQL does for us and the way it does it. That's why we've been using it for so long. We understand it, and it does the job."
"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."
"The product is easy to use and works fast for relational databases."
"It's a useful solution, that can be widely used."
"Clustering will be the number 1 feature. It is also open-source so it is free. It can also be clustered, to allow fault tolerance."
"The database has excellent performance."
"Redis is good for distributed caching management."
"Redis provides an easy setup and operation process, allowing users to quickly connect and use it without hassle."
"I find Redis valuable primarily for its caching capabilities, particularly in handling cache requests effectively. Its simplicity in managing key-value pairs for caching is one of its strengths, making it a preferred choice over more complex databases like MongoDB for specific use cases. However, I haven't explored Redis extensively for managing complex data structures beyond caching, as MongoDB might be more suitable for such scenarios."
"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."
"It makes operations more efficient. The information processing is very fast, and very responsive. It's all about the technology."
"The performance of Redis is very fast."
"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."
 

Cons

"We often find the solution's datetime datatype challenging."
"Sometimes, it becomes slow because of the network. So, there is room for improvement in performance."
"PostgreSQL could improve by adding data warehousing tools."
"PostgreSQL uses high memory compared to its counterparts when a highly demanding load is involved, especially one that makes many concurrent connections to the database."
"There are several features I would like to improve that aren't working as expected. It's likely that the latest version is doing something that was missed in the previous versions. For example, the output parameters — the stored procedures — is something new in PostgreSQL that Firebird has already had for a long time."
"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."
"I'd like to see better memory management. I think that that's one of the few areas that Postgres does not handle as well as MySQL does or did."
"I had some issues when I integrated with the Jupyter Notebook."
"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 development of clusters could improve. Additionally, it would be helpful if it was integrated with Amazon AWS or Google Cloud."
"There is a lack of documentation on the scalability of the solution."
"It's actually quite expensive."
"The initial setup took some time as our technical team needed to familiarize themselves with Redis."
"For the PubSub feature, we had to create our own tools to monitor the events."
"Redis presents a single point of failure and lacks fault tolerance."
"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

"We do not pay for licensing."
"It is open source. There is no licensing."
"It could be much cheaper. If you would like to build an application on Amazon today, PostgreSQL is the standard database with Redshift. If you want other databases, you can add them, but PostgreSQL is the basis of everything. It's a question of money, that's it."
"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."
"We use the open-source version of PostgreSQL and not the enterprise edition."
"The tool is cheaply priced compared to other RDBMS providers in the market."
"The community version of Postgre is basically free."
"Redis is not an overpriced solution."
"The tool is open-source. There are no additional costs."
"Redis is an open-source solution. There are not any hidden fees."
"We saw an ROI. It made the processing of our transactions faster."
"Redis is an open-source product."
