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

"Other technologies don’t allow the same level of scale and compute capability, while providing rigorous resilience and security underpinnings."
"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."
"It has allowed us to greatly improve our response times in several services by caching part of the database into Coherence and executing complex queries using EntryProcessors."
"Since we implemented Coherence, this data is in memory all the time; so the results are found in milliseconds instead of five seconds."
"Technical support from Oracle is okay."
"It can handle an extremely high volume of data."
"We are storing information from one of our applications; this allows us to answer requests in milliseconds, while the application would take seconds to answer requests from clients."
"I have used Oracle Coherence for more than 10 years, from version 3.5 through 12.1.2.1."
"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 ability to fetch and save data quickly is valuable."
"The in-memory data makes it fast."
"Redis acts as an in-memory search tool that improves the speed of operations, allowing for quicker data retrieval and enhancing the performance of applications."
"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."
"Overall, my experience with Redis has been very positive, and it has played a key role in improving performance, scalability, and system responsiveness in our back-end system."
"It is particularly efficient for cloud-based storage and operations."
"Redis acts as an in-memory search tool that improves the speed of operations."
 

Cons

"Customer service: Five out of 10."
"Product is too expensive and support is poor. There are better products."
"This platform has issues with stability and performance."
"It is very expensive. It might not work well for small business people."
"In my experience, I did find it challenging to use this product when namespace prefixes on the resulting XML object was a requirement."
"This platform has issues with stability and performance."
"Monitoring API needs to be improved and needs to be user friendly. Also, the error and exception handling is not that great as it can be difficult to debug issues."
"We have nodes failing all the time, especially because of timeouts caused by node synchronization, but occasionally there are also memory-related errors."
"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."
"Sometimes, we use Redis as a cluster, and the clusters can sometimes suffer some issues and bring some downtime to your application."
"Redis presents a single point of failure and lacks fault tolerance."
"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 could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."
"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."
 

Pricing and Cost Advice

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