Easy to set up with good support and good routing scenarios

The triggering and the events that they have triggered as well as the route of the message according to the events are very useful. The triggering scenarios and routing scenarios are all good. It's a very useful solution for financial institutions. The initial setup is pretty straightforward. The stability has been good. I've found the product to be scalable. Technical support is responsive.

Performance shines with seamless session caching and minimal configuration

The best features of Redis, from my personal perspective, are the performance, which is very quick, and it's very simple to implement. Since I started using Redis, I feel that the product is saving me some performance tuning time. It's very easy, I have few parameters to tune, and it seems to have performance without a lot of working on the performance, compared to Cassandra, where you have to configure the memory and many other settings. The integration capability of Redis is excellent. Redis is very affordable because it's free.

Quotes from Members

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

Pros

"I'm an administrator, and what I like most is the interface, the security, and the storage."

"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."

"The stability has been good."

"The online interface is very fast and easy to use."

"The ability to fetch and save data quickly is valuable."

"The solution is fast, provides good performance, and is not too expensive."

"Redis is a simple service that does what it promises."

"It is particularly efficient for cloud-based storage and operations."

"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."

"The best thing about Redis is its ability to handle large amounts of data without frequently hitting the database. You can store data in temporary memory, especially for high-volume data."

"The in-memory data makes it fast."

More Redis pros

Cons

"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."

"The product's interface needs improvement."

"In the next release, I would like to see the GUI allow you to configure the security section."

"It's actually quite expensive."

"The solution's pricing for a local installation is very expensive."

"If we use a lot of data, it will eventually cost us a lot."

"The initial setup of Redis was difficult, with a rating of two or three out of ten."

"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."

"There is room for AWS to provide more options for server types or a way to configure more or less memory for them."

"There is a lack of documentation on the scalability of the solution."

"Redis presents a single point of failure and lacks fault tolerance."

More Redis cons

Pricing and Cost Advice

"The platform is averagely priced."

"The pricing needs to be improved."

"We saw an ROI. It made the processing of our transactions faster."

"Redis is an open-source product."

"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."
