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

"It eases our current data flow and framework."
"We appreciate the ability to persistently and quickly write data, as well as the flexibility to customize it for multiple customers. Additionally, we like the ability to retain data within Apache Kafka and use features, such as time travel to access past customer data. The connection with other systems, such as Apache Kafka and IBM DB2."
"For example, when you want to send a message to inform all your clients about a new feature, you can publish that message to a single topic in Apache Kafka. This allows all clients subscribed to that topic to receive the message. On the other hand, if you need to send billing information to a specific customer, you can publish that message on a topic dedicated to that customer. This message can then be sent as an SMS to the customer, allowing them to view it on their mobile device."
"Apache Kafka has became our main component on almost all our distributed solutions."
"In my view, valuable features relate to microservices architecture and working on KStream and KSQL DB as a microservices event bus."
"Supports more than 10,000 events/second, scalability, and replication, and it is a good product for event-driven architecture."
"This solution is robust and delivers messages quickly."
"The processing power of Apache Kafka is good when you have requirements for high throughput and a large number of consumers."
"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."
"I'm an administrator, and what I like most is the interface, the security, and the storage."
"I am happy with the product, other than pricing I don't have any other improvements that I can suggest."
 

Cons

"The solution's initial setup process was complex."
"For the original Kafka, there is room for improvement in terms of latency spikes and resource consumption. It consumes a lot of memory."
"Kafka requires non-trivial expertise with DevOps to deploy in production at scale. The organization needs to understand ZooKeeper and Kafka and should consider using additional tools, such as MirrorMaker, so that the organization can survive an availability zone or a region going down."
"We struggled a bit with the built-in data transformations because it was a challenge to get them up and running the way we wanted."
"While the solution scales well and easily, you need to understand your future needs and prep for the peaks."
"Kafka's interface could also use some work."
"The product could be improved with proper documentation."
"It’s a trial-and-error process with no one-size-fits-all solution. Issues may arise until it’s appropriately tuned."
"The pricing needs to be improved."
"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 product's interface needs improvement."
 

Pricing and Cost Advice

"Kafka is more reasonably priced than IBM MQ."
"Apache Kafka has an open-source pricing."
"Apache Kafka is an open-sourced solution. There are fees if you want the support, and I would recommend it for enterprises. There are annual subscriptions available."
"Kafka is open-source and it is cheaper than any other product."
"This is an open-source version."
"It's a premium product, so it is not price-effective for us."
"It's quite affordable considering the value it provides."
