Event-driven architecture has improved asynchronous communication and supports high throughput
We can improve the high throughput because there are some limitations. We could add something to improve Apache Kafka. Based on my daily usage and analysis, there is a complex setup and management, which is one area requiring improvement. Apache Kafka does not have built-in message delay or scheduling capabilities. Apache Kafka cannot natively schedule messages. Limited message prioritization is also an area requiring improvement. Ordering is limited to a single partition. Large messages affect performance. Apache Kafka is optimized for many small to medium-sized messages, but large payloads increase network usage, increase disk usage, and slow down producers and consumers. I rate Apache Kafka eight out of ten instead of ten out of ten because operating an Apache Kafka cluster requires expertise in partitioning, application monitoring, and capacity planning. Self-managed deployment can become complex as the cluster grows. Pro-managed Apache Kafka services significantly reduce the operational overhead.

Efficiently calculates data flow and provides ease of integration
We seamlessly integrated IBM Event Streams with real data processes by establishing data consumers. The consumers act as end-users, initiating requests and receiving responses from the data provider. The system efficiently processes and calculates the data flow within the cluster using DLP functionality. It provides an easy integration, particularly in creating a platform and facilitating interactions between subscribers and service providers. I rate it an eight out of ten.

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."
"It just works and it's super fast."
"Other than the problems with having no control over the queue, Apache Kafka is wonderful."
"It's very easy to keep to install and it's pretty stable."
"Apache Kafka is a good solution with many good features but for large deployments, I would choose IBM MQ over Kafka."
"The message bus capabilities, basically sending messages to it, and the way it handles events or messages is pretty good."
"The main advantage is increased reliability, particularly with regard to data and the speed with which messages are published to the other side."
"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."
"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 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."
 

Cons

"The product is good, but it needs implementation and on-going support. The whole cloud engagement model has made the adoption of Kafka better due to PaaS (Amazon Kinesis, a fully managed service by AWS)."
"The UI is based on command line. It would be helpful if they could come up with a simpler user interface."
"Apache Kafka could improve data loss and compatibility with Spark."
"We haven't seen a return on investment with Apache Kafka. It's used for a specific use case rather than cost reduction."
"Too much dependency on the zookeeper and leader selection is still the bottleneck for Kafka implementation."
"Pulsar gives more scalability to an even grouping, but Apache Kafka is used more if you want to send something in a time series-based. If this does not matter to you then Pulsar could be more customizable. Apache Kafka is nothing but a streaming system with local storage."
"Kafka's interface could also use some work. Some of our products are in C, and we don't have any libraries to use with C. From an interface perspective, we had a library from the readies. And we are streaming some of the products we built to readies. That is one of the requirements. It would be good to have those libraries available in a future release for our C++ clients or public libraries, so we can include them in our product and build on that."
"An area for improvement would be growth."
"In the next release, I would like to see the GUI allow you to configure the security section."
"The pricing needs to be improved."
"The product's interface needs improvement."
"It would be helpful if they could help us explain why they, as in, the customers, should use the product and the overall benefits."
 

Pricing and Cost Advice

"Running a Kafka cluster can be expensive, especially if you need to scale it up to handle large amounts of data."
"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."
"This is an open-source solution and is free to use."
"It is approximately $600,000 USD."
"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 solution is free, it is open-source."
"It's a premium product, so it is not price-effective for us."
"I was using the product's free version."
"The platform is averagely priced."
"The pricing needs to be improved."
