Asynchronous processing has boosted throughput and supports dynamic transaction spikes
High throughput is something we aimed for, and that is the reason why we introduced Apache Kafka. Earlier, we had sequential API calls which were not scaling based on the data. Once we introduced this asynchronous architecture using Apache Kafka, high throughput was observed. That was really helpful in the overall architecture. Apache Kafka internally handles topic partitions. We design the topics and determine what kind of data storage is stored in those topics. The partition strategy is based on the kind of data model being published. We use all of those capabilities. Apache Kafka is abundant with a lot of features which only an expert-level person will be able to manage.

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 scales horizontally and scales better than its competitors."
"Apache Kafka is particularly valuable for stream data processing, handling transactions, managing high levels of transactions, and orchestrating stream mode data."
"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."
"Other than the problems with having no control over the queue, Apache Kafka is wonderful."
"It seemed pretty stable and didn't have any issues at all."
"A great streaming platform."
"It's a high-performance distributed system."
"It just works and it's super fast."
"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."
"I am happy with the product, other than pricing I don't have any other improvements that I can suggest."
"The triggering scenarios and routing scenarios are all good, making it a very useful solution for financial institutions."
 

Cons

"Scalability may cause issues in the product if my nodes are full with multiple sources and delivery is slowing down."
"The UI is based on command line. It would be helpful if they could come up with a simpler user interface."
"The third party is not very stable and sometimes you have problems with this component. There are some developments in newer versions and we're about to try them out, but I'm not sure if it closes the gap."
"The management tool could be improved."
"The GUI tools for monitoring and support are still very basic and not very rich. There is no help in determining a shard key for performance."
"More adapters for connecting to different systems need to be available."
"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."
"We cannot apply all of our security requirements because it is hard to upload them."
"The pricing needs to be improved."
"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."
"The product's interface needs improvement."
 

Pricing and Cost Advice

"I would not subscribe to the Confluent platform, but rather stay on the free open source version. The extra cost wasn't justified."
"It's quite affordable considering the value it provides."
"It is approximately $600,000 USD."
"Apache Kafka is open-source and can be used free of charge."
"The solution is free, it is open-source."
"This is an open-source version."
"The price of the solution is low."
"Kafka is an open-source solution, so there are no licensing costs."
"The platform is averagely priced."
"The pricing needs to be improved."
