Enables robust real-time data processing but documentation needs refinement
Apache Flink is very powerful, but it can be challenging for beginners because it requires prior experience with similar tools and technologies, such as Kafka and batch processing. It's essential to have a clear foundation; hence, it can be tough for beginners. However, once they grasp the concepts and have examples or references, it becomes easier. Intermediate users who are integrating with Kafka or other sources may find it smoother. After setting up and understanding the concepts, it becomes quite stable and scalable, allowing for customization of jobs. Every software, including Apache Flink, has room for improvement as it evolves. One key area for enhancement is user-friendliness and the developer experience; improving documentation and API specifications is essential, as they can currently be verbose and complex. Debugging and local testing pose challenges for newcomers, particularly when learning about concepts such as time semantics and state handling. Although the APIs exist, they aren't intuitive enough. We also need to simplify operational procedures, such as developing tools and tuning Flink clusters, as these processes can be quite complex. Additionally, implementing one-click rollback for failures and improving state management during dynamic scaling while retaining the last states is vital, as the current large states pose scaling challenges.

Stream processing has become faster and configuration time is reduced for high message volumes
Instead of using raw Kafka, Redpanda helps us manage Kafka at a production level, and it has a nice user interface so we can interact with any pending messages and processed messages. Redpanda is developer-friendly, and we need to do much less configuration because Redpanda provides out-of-the-box configuration for us. It is not only a nice UI, but it also requires less configuration compared to a raw Kafka server. Redpanda is built on top of Kafka; their main architecture is Kafka only. It has impacted us in a way that we need to do very little configuration, so we can quickly deploy Redpanda in stage, development, or production environments. We spend less time managing the raw Kafka server compared to Redpanda; Redpanda is less maintainable. Using Redpanda, we do not need a separate team that specifically manages Kafka, so we have fewer employees needed, possibly one or two less employees, and time is also saved.

Quotes from Members

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

Pros

"The documentation is very good."
"Apache Flink is meant for low latency applications. You take one event opposite if you want to maintain a certain state. When another event comes and you want to associate those events together, in-memory state management was a key feature for us."
"The setup was not too difficult."
"Apache Flink offers a range of powerful configurations and experiences for development teams. Its strength lies in its development experience and capabilities."
"The event processing function is the most useful or the most used function. The filter function and the mapping function are also very useful because we have a lot of data to transform. For example, we store a lot of information about a person, and when we want to retrieve this person's details, we need all the details. In the map function, we can actually map all persons based on their age group. That's why the mapping function is very useful. We can really get a lot of events, and then we keep on doing what we need to do."
"The top feature of Apache Flink is its low latency for fast, real-time data."
"With Flink, it provides out-of-the-box checkpointing and state management, guaranteed message processing, and it also helped us with application maintenance, deployments, and restarts."
"The main advantage is the turnaround time, which has been reduced drastically because of Apache Flink, and now everything is in almost real time with no waiting or lag of data in the application while machine resources are utilized much more efficiently."
"The UI is modern."
"I would recommend Redpanda to others because it's easy to set up, consumes less resources, and is stable compared to other tools."
"I tested it with ten-plus nodes, and it's highly scalable."
"If our infrastructure goes down for a week, we will not lose data."
"Redpanda is developer-friendly, and we need to do much less configuration because Redpanda provides out-of-the-box configuration for us."
"What makes Redpanda superior is its performance since it's written in C++. C++ is pretty much the standard for high-performance applications."
"What makes Redpanda superior is its performance since it's written in C++, which is pretty much the standard for high-performance applications."
"The cost savings have been significant."
 

Cons

"There is room for improvement in the initial setup process."
"Apache Flink's documentation should be available in more languages."
"There are more libraries that are missing and also maybe more capabilities for machine learning."
"The solution could be more user-friendly."
"Failure is another area where it is a bit rigid or not that flexible."
"The solution could be more user-friendly."
"The machine learning library is not very flexible."
"I am using the Python API and I have found the solution to be underdeveloped compared to others. There needs to be better integration with notebooks to allow for more practical development."
"The command-line tools need to be improved. To quickly check the status of the topics and all."
"Recently, for the documentation, they've built their own AI chatbot, which is focused on giving you answers based on their documentation. While using that, I did not find it to be very good."
"The command-line tools need to be improved. To quickly check the status of the topics and all."
"The version control mechanism must be improved."
