Featured Reviews

Sanjay Srivastava - PeerSpot reviewer
Software Architect at IBM
Streaming workflows have improved data integration and support real-time pipelines across platforms
We are not using Apache Flink in its advanced window capabilities. We are using the Apache Flink job in Apache SeaTunnel, meaning we can write the code inside Apache SeaTunnel. Currently, we are moving; both solutions are there. We are doing it on-premises with the help of Kubernetes and OpenShift. The main reason why Apache Flink is better is that it has more functions, and being open source with easy code in Apache SeaTunnel helps us achieve that. Cost is a major issue. I would rate the stability of the product as an eight. For Apache Flink, the final point can be rated an eight. I can recommend Apache Flink to other users for streaming support, and I am recommending it. I would rate this review an eight overall.

Event streaming has simplified video data cleanup and now powers real-time analytics
One area for improvement is providing more examples. For instance, Redpanda could be more useful as a sink where you get the data and can directly push to S3. While this is possible through the API, there are better and faster ways to do it. You can make a million API calls and accomplish the task in one and a half hours, but the same thing can be done in ten minutes through other methods. These faster approaches are not documented in obvious places. You have to find information scattered across various blogs. Redpanda should collect all the good blogs and best practices and put them in their documentation. This is more about knowledge management and making it easy for users to understand the product for complex use cases. For simple use cases, it is straightforward. We all use the basic pipe functionality. However, providing more examples would be useful. For example, integration with AWS and the AWS ecosystem would be cool.

Quotes from Members

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

Pros

"Another feature is how Flink handles its radiuses. It has something called the checkpointing concept. You're dealing with billions and billions of requests, so your system is going to fail in large storage systems. Flink handles this by using the concept of checkpointing and savepointing, where they write the aggregated state into some separate storage. So in case of failure, you can basically recall from that state and come back."
"Flink moved on to becoming a standard technology for location platform."
"This is truly a real-time solution."
"The documentation is very good."
"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."
"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."
"With Flink, it provides out-of-the-box checkpointing and state management. It helps us in that way. When Storm used to restart, sometimes we would lose messages. With Flink, it provides guaranteed message processing, which helped us. It also helped us with maintenance or restarts."
"The cost savings have been significant."
"What makes Redpanda superior is its performance since it's written in C++, which is pretty much the standard for high-performance applications."
"Redpanda was simple and fast, so we went with Redpanda and it just works."
"The performance is superb, and the value we are getting for the money we pay is great."
"I would recommend Redpanda to others because it's easy to set up, consumes less resources, and is stable compared to other tools."
"Redpanda is developer-friendly, and we need to do much less configuration because Redpanda provides out-of-the-box configuration for us."
"I tested it with ten-plus nodes, and it's highly scalable."
"Aside from its lightweight design, Redpanda is essentially a clone of Kafka with all the good features of Kafka, with the only difference being that Kafka needs too many resources while Redpanda is a very good, lightweight, and very fast database."
 

Cons

"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."
"Apache Flink's documentation should be available in more languages."
"The state maintains checkpoints and they use RocksDB or S3. They are good but sometimes the performance is affected when you use RocksDB for checkpointing."
"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."
"There is room for improvement in the initial setup process."
"In a future release, they could improve on making the error descriptions more clear."
"Apache should provide more examples and sample code related to streaming to help me better adapt and utilize the tool."
"Flink has become a lot more stable but the machine learning library is still not very flexible."
"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."
"When it comes to self-hosting, their documentation could be improved."
"One area for improvement is providing more examples."
"In Redpanda, the areas that have room for improvement are in the clustering part."
"I think Redpanda is overall very good for us, and I am uncertain whether Redpanda can scale to very large companies as we are a medium-sized startup."
 

Pricing and Cost Advice

"This is an open-source platform that can be used free of charge."
"Apache Flink is open source so we pay no licensing for the use of the software."
"The solution is open-source, which is free."
"It's an open source."
"It's an open-source solution."
"It's free. Everybody can use it, only support is paid."
