Kafka Delivers Scalable, Durable Real-Time Performance **Rating:** 5.0/5.0 stars **Reviewed by:** Aayush M. | Data Engineer - Associate, Mid-Market (51-1000 emp.) **Reviewed Date:** April 21, 2026 **What do you like best about Apache Kafka?** Best thing about Kafka is how it keep data in disk which helps it to scale and provide good performance while handling millions of real time data. It also provides high durability and we can easily go to previous offset and process same messages again in case of fault tolerance **What do you dislike about Apache Kafka?** I don't think there is any cons of Kafka but definitely it is very complex for beginner level developer to setup infrastructure and also same for consumer group. They can have good documentation for managing partitions and monitoring **What problems is Apache Kafka solving and how is that benefiting you?** Mainly it solves handling millions of real time event streams at scale. And another best thing is it keeps all logs in its disk so we can retrieve any event anytime within its duration. ### 2. Reliable Real-Time Data Streaming at Scale with Kafka **Rating:** 4.0/5.0 stars **Reviewed by:** Verified User in Retail | Enterprise (> 1000 emp.) **Reviewed Date:** April 07, 2026 **What do you like best about Apache Kafka?** What I like most is how well it handles real-time data streaming at scale. As a data engineer, we’ve used Kafka to move and process streaming data between different systems, and it’s been very reliable. It’s great for decoupling producers and consumers, so different services can operate independently without breaking the pipeline. Once it’s set up properly, it can handle high volumes of data without much issue. **What do you dislike about Apache Kafka?** The setup and maintenance can be quite heavy, especially if you’re managing it yourself. There’s a steep learning curve around topics, partitions, consumer groups, and tuning performance. Debugging issues or lag in consumers can also take time, and it’s not always obvious where the bottleneck is. It’s powerful, but definitely not the simplest tool to work with. **What problems is Apache Kafka solving and how is that benefiting you?** Kafka helped us handle real-time data streaming in a scalable and reliable way. This has made our data pipelines more responsive and flexible, especially for use cases where near real-time data is important. ### 3. Durable, High-Throughput Event Streaming with Replayable Logs **Rating:** 4.5/5.0 stars **Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.) **Reviewed Date:** March 14, 2026 **What do you like best about Apache Kafka?** Kafka gives a durable, partitioned commit-log that can handle massive throughput and lets you replay events at will, perfect for building resilient, real-time pipelines and stream processing with minimal latency. Deployment using docker is easy. Connector ecosystem is good for sink and source. **What do you dislike about Apache Kafka?** Since Kafka is JVM-based, it can feel heavier compared to some of the newer messaging systems written in Rust or C++. Those tend to have lower memory overhead and sometimes better raw performance. **What problems is Apache Kafka solving and how is that benefiting you?** Apache Kafka solves building event-driven data pipelines with minimal latency and durable, replayable delivery, making real-time analytics and stream processing straightforward. It’s excellent for high-throughput data collection and, thanks to its ecosystem of connectors, makes loading multiple sinks (including data warehouses) easy and pluggable. ### 4. Highly Scalable, Flexible Apache Kafka for Any Size Application **Rating:** 5.0/5.0 stars **Reviewed by:** Pawan M. | Senior Software Engineer, Small-Business (50 or fewer emp.) **Reviewed Date:** March 12, 2026 **What do you like best about Apache Kafka?** Apache Kafka is the best open source highly scalable Message Queue with flexible configuration and high modularity. Its perfect for smaller Proof of concept to large enterprise grade applications without the need to drastically change the tech stack **What do you dislike about Apache Kafka?** I feel the documentation could be improved so that developers who start to work in Apache Kafka would have smoother learning curve. **What problems is Apache Kafka solving and how is that benefiting you?** I have use Apache Kafka for building a distributed backend job processing pipeline. All the components works asynchronously and seamlessly scale without needing to worry much about the workload. Its one of the best way to take advantage of the job distribution and optimal hardware utilization when it comes to compute heavy workloads. ### 5. Apache kafka Streamlines Messaging with Reliable Data Queuing **Rating:** 4.5/5.0 stars **Reviewed by:** Keerthi Kumar S. | SDET, Enterprise (> 1000 emp.) **Reviewed Date:** March 10, 2026 **What do you like best about Apache Kafka?** Apache kafka is one of the best tools that I use almost daily to streamline messages. Queing of data messages makes it easier to read and execute things in order. **What do you dislike about Apache Kafka?** Sometimes the sorting functionality doesnt work which could be improved. **What problems is Apache Kafka solving and how is that benefiting you?** Apache Kafka helps me to read messages from a particular application and consume data in that particular order. This helps a lot to execute certain actions in proper order. ### 6. Apache Kafka: Real-Time Data Streaming **Rating:** 4.5/5.0 stars **Reviewed by:** Priyanka R. | Deputy Manager, Enterprise (> 1000 emp.) **Reviewed Date:** October 17, 2025 **What do you like best about Apache Kafka?** High throughput and low latency, scalability ,Durability & Fault Tolerance ,replay ability & Retention Kafka retains messages for a configurable period, allowing consumers to reprocess data or recover from failures without losing information **What do you dislike about Apache Kafka?** Operational complexity, High resource consumption, limited Message Queuing Features **What problems is Apache Kafka solving and how is that benefiting you?** Real-Time Data Streaming Kafka enables continuous, low-latency data flow between systems, making it ideal for use cases like fraud detection, recommendation engines, and live dashboards, durable and Reliable Messaging ### 7. A strong and reliable tool for real-time data streaming **Rating:** 4.5/5.0 stars **Reviewed by:** Akshat J. | Infrastructure / DevOps Engineer - 2, Mid-Market (51-1000 emp.) **Reviewed Date:** July 28, 2025 **What do you like best about Apache Kafka?** Kafka handles large volumes of data really well and is very reliable once set up properly. We use it for real-time data processing between different parts of our system. It's fast, fault-tolerant, and can scale easily when traffic grows. The publish-subscribe model makes it simple to connect producers and consumers across different services. **What do you dislike about Apache Kafka?** Initial setup and configuration can be a bit tricky, especially if you’re new to distributed systems. Managing brokers and zookeepers manually can get complex. Also, monitoring and debugging issues sometimes takes extra effort unless you have good tooling in place. **What problems is Apache Kafka solving and how is that benefiting you?** Kafka helps us move data between microservices in near real-time without delays. It’s useful for logging, metrics pipelines, user activity tracking, and even for alerting workflows. It keeps our system decoupled and helps scale better as we grow. ### 8. Unmatched Scalability and Performance for Enterprise Data Growth **Rating:** 5.0/5.0 stars **Reviewed by:** Dakalo M. | Software Developer, Small-Business (50 or fewer emp.) **Reviewed Date:** January 07, 2026 **What do you like best about Apache Kafka?** High scalability and performance making it ideal for growing data volumes in enterprises. **What do you dislike about Apache Kafka?** It requires dedicated expertise for monitoring, scaling, and maintenance.
