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 solution is scalable, and we have over a thousand users using this solution and will most likely increase the number of users because we have tested 100,000 messages per second, which is impressive."
"The most valuable feature is the performance."
"It just works and it's super fast."
"The valuable features are the group community and support."
"With Kafka, events and streaming are persistent, and multiple subscribers can consume the data. This is an advantage of Kafka compared to simple queue-based solutions."
"When we're working with big data, we need a throughput computing panel, which is something that Kafka provides, and something we find extremely valuable."
"With such a large digest, I was genuinely impressed at the process being almost real-time."
"All the features of Apache Kafka are valuable, I cannot single out one feature."
"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."
"The stability has been good."
"The triggering scenarios and routing scenarios are all good, making it a very useful solution for financial institutions."
"The system efficiently processes and calculates the data flow within the cluster using DLP functionality."
 

Cons

"Kafka requires non-trivial expertise with DevOps to deploy in production at scale."
"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."
"Kafka can allow for duplicates, which isn't as helpful in some of our scenarios."
"Apache Kafka could improve data loss and compatibility with Spark."
"would like to see real-time event-based consumption of messages rather than the traditional way through a loop. The traditional messaging system works by listing and looping with a small wait to check to see what the messages are. A push system is where you have something that is ready to receive a message and when the message comes in and hits the partition, it goes straight to the consumer versus the consumer having to pull. I believe this consumer approach is something they are working on and may come in an upcoming release. However, that is message consumption versus message listening."
"Kafka does not provide control over the message queue, so we do not know whether we are experiencing lost or duplicate messages."
"Kafka is complex and there is a little bit of a learning curve."
"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."
"In the next release, I would like to see the GUI allow you to configure the security section."
 

Pricing and Cost Advice

"Kafka is an open-source solution, so there are no licensing costs."
"I was using the product's free version."
"This is an open-source version."
"The price for the enterprise version is quite high. For on-premise, there is an annual fee, which starts at 60,000 euros, but it is usually higher than 100,000 euros. The cost for a project including the subscription is usually between 100,000 to 200,000 euros. The cost also depends on the level of support. There are two different levels of support."
"Kafka is open-source and it is cheaper than any other product."
"The price of Apache Kafka is good."
"I rate Apache Kafka's pricing a five on a scale of one to ten, where one is cheap and ten is expensive. There are no additional costs apart from the licensing fees for Apache Kafka."
"The cost can vary depending on the provider and the specific flavor or version you use. I'm not very knowledgeable about the pricing details."
"The pricing needs to be improved."
"The platform is averagely priced."
