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.

A solution with useful windowing features and great for operations and marketing
The persistence could be better. Although ESP is designed for in-memory processing, it would be better if the solution is enhanced or improved on the persistence of the data that is kept in the memory. For example, if one server goes down and the information is stored in the memory, it is lost. Therefore, the persistence needs to be improved so that if there are more cases where the server is down, the information and data can still be intact.

Quotes from Members

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

Pros

"As a software developer, I have found Apache Kafka's support to be the most valuable...The solution is easy to integrate with any of our systems."
"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 solution is very easy to set up."
"This solution is robust and delivers messages quickly."
"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."
"I like the performance and reliability of Kafka, as I needed a data streaming buffer that could handle thousands of messages per second with at least one processing point for an analytics pipeline, and Kafka fits this requirement very well, as it is a fast, distributed message broker that does exactly what it is designed to do."
"Apache Kafka is actually a distributed commit log. That is different than most messaging and queuing systems before it."
"The main advantage is increased reliability, particularly with regard to data and the speed with which messages are published to the other side."
"The solution is beneficial on an enterprise level."
 

Cons

"As an open-source project, Kafka is still fairly young and has not yet built out the stability and features that other open-source projects have acquired over the many years. If done correctly, Kafka can also take over the stream-processing space that technologies such as Apache Storm cover."
"Kafka does not provide control over the message queue, so we do not know whether we are experiencing lost or duplicate messages."
"The support from Apache Kafka could improve. Their engineers at times do not know what the solutions can do."
"The speed isn't as fast as RabbitMQ, even though the solution touts itself as very quick."
"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."
"It needs a separate cluster and a separate administrator to manage the Kafka cluster, adding an extra cost."
"When compared to other commercial competitors, Kafka doesn't have the ability to scale down, the elasticity is lacking in the product."
"The only reason I give Kafka as product a low rating is because there are far superior and cheaper alternatives in cloud-based solutions, where we save money on manpower, electricity, servers, datacenters, networking, etc."
"The persistence could be better."
 

Pricing and Cost Advice

"I was using the product's free version."
"The solution is open source."
"It's a premium product, so it is not price-effective for us."
"The price for the enterprise version is quite high. For on-premise, there is an annual fee, which starts at 60,000 euros, but it is usually higher than 100,000 euros. The cost for a project including the subscription is usually between 100,000 to 200,000 euros. The cost also depends on the level of support. There are two different levels of support."
"It's a bit cheaper compared to other Q applications."
"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."
"Apache Kafka is an open-source solution and there are no fees, but there are fees associated with confluence, which are based on subscription."
"I would not subscribe to the Confluent platform, but rather stay on the free open source version. The extra cost wasn't justified."
