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.

Has supported streaming use cases across data centers and simplifies fraud analytics with SQL-based processing

I recommend that Confluent should improve its solution to keep up with competitors in the market, such as Solace and other upcoming tools such as NATS. Recently, there has been a lot of buzz about Confluent charging high fees while not offering features that match those of other tools. They need to improve in that direction by not only reducing costs but also providing better solutions for the problems customers face to avoid frustrations, whether through future enhancement requests or ensuring product stability. The cost should be worked on, and they should provide better solutions for customers. Solutions should focus on hierarchical topics; if a customer has different types of data and sources, they should be able to send them to the same place for analytics. Currently, Confluent requires everything to send to the same topic, which becomes very large and makes running analytics difficult. The hierarchy of topics should be improved. This part is available in MQ and other products such as Solace, but it is missing in Confluent, leading many in capital markets and trading to switch to Solace. In terms of stability, it is not the stability itself that needs improvement but rather the delivery semantics. Other products offer exactly-once delivery out of the box, whereas Confluent states it will offer this but lacks the knobs or levers for tuning configurations effectively. Confluent has hundreds of configurations that application teams must understand, which creates a gap. Users are often unaware of what values to set for better performance or to achieve exactly-once semantics, making it difficult to navigate through them. Delivery semantics also need to be worked on.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"Apache Kafka's most valuable features include clustering and sharding...It is a pretty stable solution."

"Kafka is an open-source tool that's easy to use in our country, and the command line interface is powerful."

"It has become dead simple to connect different application and services, saving a lot of development hours."

"Some of the clusters churn millions of records per seconds with ease."

"The ability to partition data on Kafka is valuable."

"Apache Kafka is an open-source solution that can be used for messaging or event processing."

"Kafka can process messages in real-time, making it useful for applications that require near-instantaneous processing."

"We used to lose some of our messages when we integrated them in bulk, this solution has stopped that happening."

More Apache Kafka pros

"We ensure seamless management of Kafka through Confluent, allowing all of our Kafka activities to be handled by a third party."

"The benefit is escaping email communication. Sometimes people ignore emails or put them into spam, but with Confluence, everyone sees the same text at the same time."

"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."

"Some of the best features are that it's very quick to set up, very easy to have a centralized area that gives us a history of changes, and the ability to give feedback on any information placed onto the pages."

"Their tech support is amazing; they are very good, both on and off-site."

"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."

"With Confluent Cloud we no longer need to handle the infrastructure and the plumbing, which is a concern for Confluent, and the other advantage is that all portfolios have access to the data that is being shared."

"Implementing Confluent's schema registry has significantly enhanced our organization's data quality assurance."

More Confluent pros

Cons

"More Windows support, I believe, is one area where it can improve. We need to wrap it as a service, but there isn't one built into Windows."

"Stability of the API and the technical support could be improved."

"We used to have problems in Kafka every three weeks and our dev ops team fixed a few issues."

"The support on Apache Kafka could be improved."

"The ability to connect the producers and consumers must be improved."

"Scalability may cause issues in the product if my nodes are full with multiple sources and delivery is slowing 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."

"We struggled a bit with the built-in data transformations because it was a challenge to get them up and running the way we wanted."

More Apache Kafka cons

"Confluent's price needs improvement."

"Confluence could improve the server version of the solution. However, most companies are going to the cloud."

"The solution could have an extra plugin or upgrading feature. In addition, it could have more integration with different platforms and be more compatible."

"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."

"The formatting aspect within the page can be improved and more powerful."

"It could be improved by including a feature that automatically creates a new topic and puts failed messages."

"Recently, there has been a lot of buzz about Confluent charging high fees while not offering features that match those of other tools."

"Areas for improvement include implementing multi-storage support to differentiate between database stores based on data age and optimizing storage costs."

More Confluent cons

More Apache Kafka pricing and cost advice

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

"Confluent is highly priced."

"It comes with a high cost."

"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."

"The solution is cheaper than other products."

"You have to pay additional for one or two features."

"Confluent is expensive, I would prefer, Apache Kafka over Confluent because of the high cost of maintenance."

"Confluent has a yearly license, which is a bit high because it's on a per-user basis."
