Room For Improvement

Kafka needs improvements in duplicate management, UI, troubleshooting, cloud integration, messaging control, ZooKeeper dependency, and management tools.
Apache Kafka on Confluent Cloud needs improvements in integrations, user interface, cost, monitoring, and configuration for enhanced functionality.
The performance angle is critical, and while it works in milliseconds, the goal is to move towards microseconds.
Technology Leader at eTCaaS
Running and maintaining an Apache Kafka cluster at scale involves handling partitions, replications, retention policies, rebalancing, and monitoring, which requires strong expertise.
Senior Software Developer at NIT
Apache Kafka groups could introduce themes or profiles of configuration to help manage this complexity without needing expertise.
Senior Principal Architect at a computer software company with 501-1,000 employees
If it were easier to configure clusters and had more straightforward configuration, high-level API abstraction in the APIs could improve it.
Partner at SouJava
Regarding additional improvements, I would say probably around error handling, where when we encounter errors specific to our response structures and everything, or the tables or anything of that nature, it would be better if we were prompted with better error handling mechanisms.
Lead Software Engineer at a tech vendor with 10,001+ employees
Observability and monitoring are areas that could be enhanced.
Chief Architect at a financial services firm with 10,001+ employees
 

Setup Cost

Apache Kafka is open-source and affordable, but managed services and support can incur additional costs.
Enterprise users of Apache Kafka on Confluent Cloud find pricing accessible but warn of potential cost surges with added features.
From a price perspective, if you are asking about Apache Kafka, I would rate it a nine.
Senior Principal Architect at a computer software company with 501-1,000 employees
The open-source version of Apache Kafka results in minimal costs, mainly linked to accessing documentation and limited support.
Technology Leader at eTCaaS
Its pricing is reasonable.
I thought Confluent would stop me when I crossed the credits, but it did not, and then I got charged.
Lead Software Engineer at a tech vendor with 10,001+ employees
 

Valuable Features

Apache Kafka provides scalable, fault-tolerant, real-time data streaming for reliable message processing and integration across platforms with open-source flexibility.
Apache Kafka on Confluent Cloud enables scalable, efficient real-time data processing with seamless platform integration and advanced management features.
Apache Kafka is effective when dealing with large volumes of data flowing at high speeds, requiring real-time processing.
Apache Kafka is particularly valuable for managing high levels of transactions.
Senior Manager at Timestamp, SA
Regarding durability and reliability, messages are persisted, so temporary consumer failures do not automatically lead to data loss, which is valuable in financial workflows where losing events is unacceptable.
Senior Software Developer at NIT
These features are important due to scalability and resiliency.
Chief Architect at a financial services firm with 10,001+ employees
The Kafka Streams API helps with real-time data transformations and aggregations.
Partner at SouJava
The best features Apache Kafka on Confluent Cloud offers would be the connection with various external systems through various languages such as Python and C#.

Senior Software Developer at NIT
Event-driven workflows have improved payment processing and reduced latency across services
One area for improvement in Apache Kafka is operational complexity. Running and maintaining an Apache Kafka cluster at scale involves handling partitions, replications, retention policies, rebalancing, and monitoring, which requires strong expertise. Debugging and observability can be complex in large systems, as troubleshooting issues such as consumer lag, offset management problems, or uneven partition distribution can become challenging. The learning curve is relatively steep, requiring a good understanding of concepts such as partition, consumer group, offset commit, and delivery guarantees to avoid subtle production issues. One area where Apache Kafka could improve is the developer experience around debugging and tracing events end to end. In distributed systems, when an event passes through multiple topics and consumer services, troubleshooting can become time-consuming. Better built-in observability for tracing event flows across services would be very useful.

Has unified log streams from multiple systems and accelerated issue tracking through streamlined setup
I think Apache Kafka on Confluent Cloud can be improved by probably working more around Confluent or the tool. In my opinion, it should utilize the response structures in a better way or be able to detect if there is any variable or if there is any data structure that is mismatched, as it would be easier than us manually having to put in the exact name in order for it to match the response. Regarding additional improvements, I would say probably around error handling, where when we encounter errors specific to our response structures and everything, or the tables or anything of that nature, it would be better if we were prompted with better error handling mechanisms. I do not think there are any other improvements Apache Kafka on Confluent Cloud needs, aside from error handling and response structures.
