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 most valuable feature is the messaging function and reliability."
"Robust and delivers messages quickly."
"The most valuable feature is the performance."
"The stability is very nice. We currently manage 50 million events daily."
"The most important feature for me is the guaranteed delivery of messages from producers to consumers."
"The connectors provided by the solution are valuable."
"Apache Kafka is actually a distributed commit log. That is different than most messaging and queuing systems before it."
"Kafka, as compared with other messaging system options, is great for large scale message processing applications. It offers high throughput with built-in fault-tolerance and replication."
"One of the best features of Confluent is that it's very easy to search and have a live status with Jira."
"Implementing Confluent's schema registry has significantly enhanced our organization's data quality assurance."
"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."
"Their tech support is amazing; they are very good, both on and off-site."
"The documentation process is fast with the tool."
"Confluence's greatest asset is its user-friendly interface, coupled with its remarkable ability to seamlessly integrate with a vast range of other solutions."
"The client APIs are the most valuable feature."
"The most valuable feature of Confluent is the wide range of features provided. They're leading the market in this category."
 

Cons

"One of the things I am mostly looking for is that once the message is picked up from Kafka, it should not be visible or able to be consumed by other applications, or something along those lines. That feature is not present, but it is not a limitation or anything of the sort; rather, it is a desirable feature. The next release should include a feature that prevents messages from being consumed by other applications once they are picked up by Kafka."
"The UI is based on command line. It would be helpful if they could come up with a simpler user interface."
"Config management can be better. We are always trying to find the best configs, which is a challenge."
"Kafka is complex and there is a little bit of a learning curve."
"Lacks elasticity and the ability to scale down."
"Kafka 2.0 has been released for over a month, and I wanted to try out the new features. However, the configuration is a little bit complicated: Kafka Broker, Kafka Manager, ZooKeeper Servers, etc."
"Apache Kafka has performance issues that cause it to lag."
"I suggest using cloud services because the solution is expensive if you are using it on-premises."
"In Confluent, there could be a few more VPN options."
"Confluence could improve the server version of the solution. However, most companies are going to the cloud."
"Areas for improvement include implementing multi-storage support to differentiate between database stores based on data age and optimizing storage costs."
"Confluent has a good monitoring tool, but it's not customizable."
"The formatting aspect within the page can be improved and more powerful."
"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."
"Confluent's price needs improvement."
"It could have more integration with different platforms."
 

Pricing and Cost Advice

"Confluent is an expensive solution as we went for a three contract and it was very costly for us."

"The solution is cheaper than other products."
"You have to pay additional for one or two features."
"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 highly priced."
"It comes with a high cost."
