Event-driven workflows have improved payment processing and reduced latency across services
One area for improvement in Apache Kafka is operational complexity. Running and maintaining an Apache Kafka cluster at scale involves handling partitions, replications, retention policies, rebalancing, and monitoring, which requires strong expertise. Debugging and observability can be complex in large systems, as troubleshooting issues such as consumer lag, offset management problems, or uneven partition distribution can become challenging. The learning curve is relatively steep, requiring a good understanding of concepts such as partition, consumer group, offset commit, and delivery guarantees to avoid subtle production issues. One area where Apache Kafka could improve is the developer experience around debugging and tracing events end to end. In distributed systems, when an event passes through multiple topics and consumer services, troubleshooting can become time-consuming. Better built-in observability for tracing event flows across services would be very useful.

Easy to use, stable, has a good interface, and the security is good
I don't know if it's because of experience, but for me, it was easy to install. It's just a matter of having an RPM, then click next, next, and next again. The difficult part comes in when you have to configure the security. That is the most difficult part, but it's not that difficult. It takes less than two hours to install. Two hours max, because I did one yesterday. I installed it on AWS and it was easy to install the software. It was less than an hour for the bare minimum installation. Setting up the security, took close to two hours.

Quotes from Members

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

Pros

"The ability to partition data on Kafka is valuable."
"I use it for real-time processing workloads. So, in some instances, it's like IoT data. We need to put it into a data lake."
"Excellent speeds for publishing messages faster."
"The most valuable feature is the speed at which the solution can be deployed."
"The publisher-subscriber pattern and low latency are also essential features that greatly piqued my interest."
"We implemented the notification system between our components, and we found that Apache Kafka performs well in scalability, improving our organization because of the scalability and the comfort of a fail-safe or disaster recovery it provides."
"Kafka, as compared with other messaging system options, is great for large scale message processing applications. It offers high throughput with built-in fault-tolerance and replication."
"The use of Kafka's logging mechanism has been extremely beneficial for us, as it allows us to sequence messages, track pointers, and manage memory without having to create multiple copies."
"The stability has been good."
"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."
"The triggering scenarios and routing scenarios are all good, making it a very useful solution for financial institutions."
"I am happy with the product, other than pricing I don't have any other improvements that I can suggest."
"I'm an administrator, and what I like most is the interface, the security, and the storage."
 

Cons

"The price for the enterprise version is quite high. It would be better to have a lower price."
"The solution can improve by having automation for developers. We have done many manual calculations and it has been difficult but if it was automated it would be much better."
"The repository isn't working very well. It's not user friendly."
"Maintaining and configuring Apache Kafka can be challenging, especially when you want to fine-tune its behavior."
"As an open-source project, Kafka is still fairly young and has not yet built out the stability and features that other open-source projects have acquired over the many years. If done correctly, Kafka can also take over the stream-processing space that technologies such as Apache Storm cover."
"Data pulling and restart ability need improving."
"In the data sharing space, the performance of Apache Kafka could be improved. The performance angle is critical, and while it works in milliseconds, the goal is to move towards microseconds."
"The standard Kafka Java library, which is shipped with the product, is too complex for inexperienced users."
"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."
"In the next release, I would like to see the GUI allow you to configure the security section."
"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 pricing needs to be improved."
"The product's interface needs improvement."
 

Pricing and Cost Advice

"The solution is open source; it's free to use."
"Kafka is more reasonably priced than IBM MQ."
"It is open source software."
"I was using the product's free version."
"This is an open-source version."
"Running a Kafka cluster can be expensive, especially if you need to scale it up to handle large amounts of data."
"It's quite affordable considering the value it provides."
"Apache Kafka is an open-source solution and there are no fees, but there are fees associated with confluence, which are based on subscription."
"The pricing needs to be improved."
"The platform is averagely priced."
