Amandeep Pawar - PeerSpot reviewer
Engineer Technology at Iris Software Technologies Private Limited
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.

Solution Architect at Vlaanderen connect.
The solution can mimic other APIs without changing a line of code
The solution operates as a classic message broker but also as a streaming platform. It operates differently than a traditional streaming platform with storage and computing handled separately. It scales easier and better than Kafka which can be stubborn. You can even make it act like Kafka because it understands Kafka APIs. There are even companies that will sell you Kafka but underneath it is Apache Pulsar. The solution is very compatible because it can mimic other APIs without changing a line of code.

Quotes from Members

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

Pros

"Kafka can process messages in real-time, making it useful for applications that require near-instantaneous processing."
"The most valuable feature of Apache Kafka is Kafka Connect."
"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."
"The most valuable feature is the speed at which the solution can be deployed."
"Kafka was at the base of our system architecture."
"Apache Kafka is scalable. It is easy to add brokers."
"The most valuable feature of Kafka is the Kafka Streams client."
"There are numerous possibilities that can be explored. While it may be challenging to fully comprehend the potential advantages, one key aspect is the ability to establish a proper sequence of events rather than simply dealing with a jumbled group of occurrences. These events possess their own timestamps, even if they were not initially provided with one, and are arranged in a chronological order that allows for a clear understanding of the progression of the events."
"The solution operates as a classic message broker but also as a streaming platform."
 

Cons

"The solution can improve its cloud support."
"When compared to other commercial competitors, Kafka doesn't have the ability to scale down, the elasticity is lacking in the product."
"The UI used to access Kafka topics can be further improved."
"Confluent has improved aspects like documentation and cloud support, yet Kafka's reliance on older architectures like ZooKeeper in previous versions is a limitation."
"Kafka has a lot of monitors, but sometimes it's most important to just have a simple monitor."
"The initial setup and deployment could be less complex."
"Kafka requires non-trivial expertise with DevOps to deploy in production at scale."
"Lacks elasticity and the ability to scale down."
"Documentation is poor because much of it is in Chinese with no English translation."
 

Pricing and Cost Advice

"The price of Apache Kafka is good."
"Running a Kafka cluster can be expensive, especially if you need to scale it up to handle large amounts of data."
"Apache Kafka is free."
"This is an open-source solution and is free to use."
"Kafka is more reasonably priced than IBM MQ."
"Apache Kafka has an open-source pricing."
"Apache Kafka is an open-sourced solution. There are fees if you want the support, and I would recommend it for enterprises. There are annual subscriptions available."
"It is open source software."
