Facilitating real-time business insights with enhanced data querying
Coherence is beneficial due to its multi-indexing to the same object and filtering based on data attributes within the object, followed by aggregation. These features facilitate querying data with multiple keys rather than just a single key. Its real-time data processing capabilities provide insights for business decisions with up-to-date information.

Caching has accelerated complex workflows and delivers low latency for high-traffic microservices
A few features of Redis that I use on a day-to-day basis and feel are among the best are extremely low latency and high throughput. Since Redis is in-memory, it makes it ideal for cases such as caching and rate limiting where response time is critical. TTL expiry support is very useful in Redis as it allows me to automatically evict stale data without manual cleanup, which is something I use heavily in my caching strategy. Another point I can mention is that the rich data structures such as strings, hashes, and even sorted sets are very powerful. I have used strings for caching responses and counters, whereas I have used hashes for storing structured objects. One more feature I can tell you about is atomic operations. Redis guarantees atomicity for operations such as incrementing a counter, which is very useful for rate limiting and avoiding race conditions in distributed systems. Finally, I want to emphasize that Redis is easy to scale and integrate, whether through clustering or using a distributed cache across microservices. Redis has impacted my organization positively by providing default support that is very useful. For metrics, in one of my core systems, introducing Redis as a distributed cache helped me achieve around an 80% cache hit rate, which reduced repeated downstream services. Real API latency also improved from around two seconds to approximately 450 milliseconds for P99. It also helped reduce the load on dependent services and databases, which improved overall system reliability.

Quotes from Members

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

Pros

"The product is great, simple, and easy to use and integrate."
"Introducing a data grid, we moved from a vertically scalable solution to full scalability."
"For high-end solutions, involving advanced features, Coherence outstands competitors, fully justifying its price tag."
"In my experience, while working on customers’ solutions where performance is a key requirement, along with robustness and stability needs, I have always found Oracle Coherence as the best solution for integrating with different Oracle products and caching data for application-specific needs."
"Since we implemented Coherence, this data is in memory all the time; so the results are found in milliseconds instead of five seconds."
"Coherence absolutely outperforms others in terms of scalability, reliability, and performance."
"The biggest improvement is in speed - everything is faster from record retrieval to workflow processing."
"A single logical cache scattered across various geographies ensured we had only one cache to look against (location transparency) at the same time, ensuring high availability."
"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."
"Overall, I want to say that Redis truly adds value, especially for low latency and high throughput use cases."
"The solution is fast, provides good performance, and is not too expensive."
"The product offers fast access to my database."
"Redis acts as an in-memory search tool that improves the speed of operations."
"It is particularly efficient for cloud-based storage and operations."
"Redis is good for distributed caching management."
"It makes operations more efficient. The information processing is very fast, and very responsive. It's all about the technology."
 

Cons

"Product is too expensive and support is poor. There are better products."
"The price is high. I believe there should be a cheaper version for only the caching solution."
"The product is the best, but it's absurdly expensive because licensing is according to the number of CPUs."
"Technical support is 3 or even 2 out of 10. Working directly through an account rep or a contact on Coherence dev team helps a lot."
"Data transfer performance over geographical locations. Oracle database has better performance compared to Coherence when accessed from different regions."
"It is very expensive. It might not work well for small business people."
"We have encountered the occasional minor bug and very occasional more serious bug."
"Initial setup was complex. We wrote a lot of wrapper code around the Coherence libraries in order to make it easier for the developer."
"The initial setup of Redis was difficult, with a rating of two or three out of ten."
"There is a lack of documentation on the scalability of the solution."
"The initial setup took some time as our technical team needed to familiarize themselves with Redis."
"It's actually quite expensive."
"The development of clusters could improve. Additionally, it would be helpful if it was integrated with Amazon AWS or Google Cloud."
"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."
"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."
"There is room for AWS to provide more options for server types or a way to configure more or less memory for them."
 

Pricing and Cost Advice

Information not available
"We saw an ROI. It made the processing of our transactions faster."
"The tool is open-source. There are no additional costs."
"Redis is not an overpriced solution."
"Redis is an open-source product."
"Redis is an open-source solution. There are not any hidden fees."
