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

"Coherence has improved response times for queries of sizeable data sets, and by allowing for data distribution and replication through clustering, it improves the reliability of information systems."
"This product helped our organization to focus on implementing business logic without worrying about scalability on user loads of huge data queries."
"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."
"High availability, distributed calculation features, and WebLogic integration are the most valuable features to me."
"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."
"Technical support from Oracle is okay."
"The Customer Facing Application response time has been improved 95%."
"Portable object format (POF serialization) allows objects to be serialized and deserialized between Java and .NET so the two platforms can exchange data seamlessly."
"Redis is a simple, powerful, and fast solution."
"The in-memory data makes it fast."
"Redis is good for distributed caching management."
"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 online interface is very fast and easy to use."
"Since I started using Redis, I feel that the product is saving me some performance tuning time."
"I use Redis mostly to cache repeated data that is required."
"Redis has multiple valuable features such as being a free and reliable open-source tool."
 

Cons

"The initial setup is complex and time-consuming."
"Data transfer performance over geographical locations. Oracle database has better performance compared to Coherence when accessed from different regions."
"Due to the licensing prices, we are looking for other solutions as an alternative to Coherence."
"It has become very heavy along with the price for Oracle's integrated product as a fusion middleware."
"The product is the best, but it's absurdly expensive because licensing is according to the number of CPUs."
"Oracle Coherence has considerable operational risks."
"I would like to see a more modern API like Hazelcast or Infinispan."
"OSB could be tuned to do things like Apigee."
"For the PubSub feature, we had to create our own tools to monitor the events."
"The initial setup of Redis was difficult, with a rating of two or three out of ten."
"It's actually quite expensive."
"The tool should improve by increasing its size limits and handling dynamic data better. We use the client ID or associate it with a key for static content. The solution will not be easy for a beginner. Unless you understand SQL data, it will be difficult to understand and use Redis. It also needs to be user-friendly."
"Redis could improve its efficiency in handling locally stored data, not just Amazon Cloud or Google Cloud."
"There is room for AWS to provide more options for server types or a way to configure more or less memory for them."
"Sometimes, we use Redis as a cluster, and the clusters can sometimes suffer some issues and bring some downtime to your application."
"Managing memory efficiently and troubleshooting issues can sometimes require additional tooling, so these areas can also be improved."
