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

"One of the most valuable features I have found is Kafka Connect."
"Apache Kafka offers unique data streaming."
"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."
"The main advantage is increased reliability, particularly with regard to data and the speed with which messages are published to the other side."
"The stability is very nice. We currently manage 50 million events daily."
"The most valuable feature is the support for a high volume of data."
"Kafka provides us with a way to store the data used for analytics. That's the big selling point. There's very good log management."
"Apache Kafka is an open-source solution that can be used for messaging or event processing."
"Confluent facilitates the messaging tasks with Kafka, streamlining our processes effectively."
"The most valuable feature that we are using is the data replication between the data centers allowing us to configure a disaster recovery or software. However, is it's not mandatory to use and because most of the features that we use are from Apache Kafka, such as end-to-end encryption. Internally, we can develop our own kind of product or service from Apache Kafka."
"Our main goal is to validate whether we can build a scalable and cost-efficient way to replicate data from these various sources."
"Confluence's greatest asset is its user-friendly interface, coupled with its remarkable ability to seamlessly integrate with a vast range of other solutions."
"A person with a good IT background and HTML will not have any trouble with Confluent."
"The client APIs are the most valuable feature."
"The design of the product is extremely well built and it is highly configurable."
"Their tech support is amazing; they are very good, both on and off-site."
 

Cons

"Data pulling and restart ability need improving."
"There have been some challenges with monitoring Apache Kafka, as there are currently only a few production-grade solutions available, which are all under enterprise license and therefore not easily accessible. The speaker has not had access to any of these solutions and has instead relied on tools, such as Dynatrace, which do not provide sufficient insight into the Apache Kafka system. While there are other tools available, they do not offer the same level of real-time data as enterprise solutions."
"In Apache Kafka, it is currently difficult to create a consumer."
"The manageability should be improved. There are lots of things we need to manage and it should have a function that enables us to manage them all cohesively."
"The solution could always add a few more features to enhance its usage."
"Maintaining and configuring Apache Kafka can be challenging, especially when you want to fine-tune its behavior."
"Stability of the API and the technical support could be improved."
"We cannot apply all of our security requirements because it is hard to upload them."
"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."
"there is room for improvement in the visualization."
"Areas for improvement include implementing multi-storage support to differentiate between database stores based on data age and optimizing storage costs."
"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 more user-friendly and centralized. A way to reduce redundancy would be helpful."
"One area we've identified that could be improved is the governance and access control to the Kafka topics. We've found some limitations, like a threshold of 10,000 rules per cluster, that make it challenging to manage access at scale if we have many different data sources."
"The formatting aspect within the page can be improved and more powerful."
 

Pricing and Cost Advice

"Apache Kafka is an open-source solution."
"It is approximately $600,000 USD."
"Licensing issues are not applicable. Apache licensing makes it simple with almost zero cost for the software itself."
"I would not subscribe to the Confluent platform, but rather stay on the free open source version. The extra cost wasn't justified."
"Kafka is open-source and it is cheaper than any other product."
"The solution is open source."
"Kafka is more reasonably priced than IBM MQ."
"We are using the free version of Apache Kafka."
"Confluent has a yearly license, which is a bit high because it's on a per-user basis."
"Confluent is an expensive solution as we went for a three contract and it was very costly for us."
"The pricing model of Confluent could improve because if you have a classic use case where you're going to use all the features there is no plan to reduce the features. You should be able to pick and choose basic services at a reduced price. The pricing was high for our needs. We should not have to pay for features we do not use."
"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."
"It comes with a high cost."
"The solution is cheaper than other products."
"You have to pay additional for one or two features."
"Confluent is highly priced."
