Data streaming transforms real-time data movement with impressive scalability
I worked with Apache Kafka for customers in the financial industry and OTT platforms. They use Kafka particularly for data streaming. Companies offering movie and entertainment as a service, similar to Netflix, use Kafka Apache Kafka offers unique data streaming. It allows the use of data in…
Gustavo-Barbosa Dos Santos - PeerSpot reviewer
Has good technical support services and a valuable feature for real-time data streaming
Implementing Confluent's schema registry has significantly enhanced our organization's data quality assurance. It helps us understand the various requirements of multiple customers and validates the information for different versions. We can automate the tasks using Confluent Kafka. Thus, it guarantees us the data quality and maintains the integrity of message contracts.

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."
"The most valuable feature of Apache Kafka is Kafka Connect."
"The high availability is valuable. It is robust, and we can rely on it for a huge amount of data."
"Overall, I rate Apache Kafka as nine out of ten for its scalability and stability."
"Excellent speeds for publishing messages faster."
"I like the performance and reliability of Kafka. I needed a data streaming buffer that could handle thousands of messages per second with at least one processing point for an analytics pipeline. Kafka fits this requirement very well."
"The most valuable feature is the messaging function and reliability."
"Its availability is brilliant."
"The solution can handle a high volume of data because it works and scales well."
"The client APIs are the most valuable feature."
"I would rate the scalability of the solution at eight out of ten. We have 20 people who use Confluent in our organization now, and we hope to increase usage in the future."
"I find Confluent's Kafka Connectors and Kafka Streams invaluable for my use cases because they simplify real-time data processing and ETL tasks by providing reliable, pre-packaged connectors and tools."
"The monitoring module is impressive."
"The documentation process is fast with the tool."
"Their tech support is amazing; they are very good, both on and off-site."
"Confluence's greatest asset is its user-friendly interface, coupled with its remarkable ability to seamlessly integrate with a vast range of other solutions."
 

Cons

"We haven't seen a return on investment with Apache Kafka. It's used for a specific use case rather than cost reduction."
"Managing Apache Kafka can be a challenge, but there are solutions. I used the newest release, as it seems they have removed Zookeeper, which should make it easier. Confluent provides a fully managed Kafka platform, in which the cluster does not need to be managed."
"The interface has room for improvement, and there is a steep learning curve for Hadoop integration. It was a struggle learning to send from Hadoop to Kafka. In future releases, I'd like to see improvements in ETL functionality and Hadoop integration."
"The management tool could be improved."
"Config management can be better. We are always trying to find the best configs, which is a challenge."
"More adapters for connecting to different systems need to be available."
"The solution could always add a few more features to enhance its usage."
"The support on Apache Kafka could be improved."
"It requires some application specific connectors which are lacking. This needs to be added."
"there is room for improvement in the visualization."
"It could be more user-friendly and centralized. A way to reduce redundancy would be helpful."
"The product should integrate tools for incorporating diagrams like Lucidchart. It also needs to improve its formatting features. We also faced issues while granting permissions."
"I am not very impressed by Confluent. We continuously face issues, such as Kafka being down and slow responses from the support team."
"Currently, in the early stages, I see a gap on the security side. If you are using the SaaS version, we would like to get a fuller, more secure solution that can be adopted right out of the box. Confluence could do a better job sharing best practices or a reusable pattern that others have used, especially for companies that can not afford to hire professional services from Confluent."
"It could be improved by including a feature that automatically creates a new topic and puts failed messages."
"The pricing model should include the ability to pick features and be charged for them only."
 

Pricing and Cost Advice

"Apache Kafka has an open-source pricing."
"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."
"Kafka is open-source and it is cheaper than any other product."
"Running a Kafka cluster can be expensive, especially if you need to scale it up to handle large amounts of data."
"This is an open-source solution and is free to use."
"I was using the product's free version."
"Apache Kafka is an open-source solution."
"We are using the free version of Apache Kafka."
"Confluence's pricing is quite reasonable, with a cost of around $10 per user that decreases as the number of users increases. Additionally, it's worth noting that for teams of up to 10 users, the solution is completely free."
"Confluent is an expensive solution as we went for a three contract and it was very costly for us."
"You have to pay additional for one or two features."
"Confluent is an expensive solution."
"Confluent is highly priced."
"On a scale from one to ten, where one is low pricing and ten is high pricing, I would rate Confluent's pricing at five. I have not encountered any additional costs."
"Confluent is expensive, I would prefer, Apache Kafka over Confluent because of the high cost of maintenance."
"Regarding pricing, I think Confluent is a premium product, but it's hard for me to say definitively if it's overly expensive. We're still trying to understand if the features and reduced maintenance complexity justify the cost, especially as we scale our platform use."
