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

"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."

"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."

"The end-to-end latency was drastically reduced, and our capability of handling high throughput has increased by using Flink."

"It provides us the flexibility to deploy it on any cluster without being constrained by cloud-based limitations."

"The ease of usage, even for complex tasks, stands out."

"The documentation is very good."

"We value this solution's intricate system because it comes with a state inside the mechanism and product, allowing us to process batch data, stream to real-time and build pipelines, and we do not need to process data from the beginning when we pause as we can continue from the same point where we stopped, helping us save time as 95% of our pipelines will now be on Amazon and we'll save money by saving time."

"Easy to deploy and manage."

More Apache Flink pros

"I do want to mention that there was a part of Redpanda where you can configure and create containers with Docker."

"The performance is superb, and the value we are getting for the money we pay is great."

"Redpanda has positively impacted my organization because the process is now easy and we have not used another streaming platform for comparison, but it has been better than Kafka."

"Through a lot of benchmarks and whatnot, we found out that on a larger scale, when the latency of the messages is important, not talking about throughput, the latency is important, Redpanda offers a way better latency profile than Apache Kafka."

"I tested it with ten-plus nodes, and it's highly scalable."

"The good part about Redpanda is that there is a free part, which is great, and it is embedding most Kafka features so you have a number of features similar to Confluent but for free, which is great."

"Redpanda was simple and fast, so we went with Redpanda and it just works."

"Redpanda is developer-friendly, and we need to do much less configuration because Redpanda provides out-of-the-box configuration for us."

More Redpanda pros

Cons

"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."

"PyFlink is not as fully featured as Python itself, so there are some limitations to what you can do with it."

"Flink has become a lot more stable but the machine learning library is still not very flexible."

"In terms of improvement, there should be better reporting. You can integrate with reporting solutions but Flink doesn't offer it themselves."

"Failure is another area where it is a bit rigid or not that flexible."

"One way to improve Flink would be to enhance integration between different ecosystems. For example, there could be more integration with other big data vendors and platforms similar in scope to how Apache Flink works with Cloudera. Apache Flink is a part of the same ecosystem as Cloudera, and for batch processing it's actually very useful but for real-time processing there could be more development with regards to the big data capabilities amongst the various ecosystems out there."

"Apache should provide more examples and sample code related to streaming to help me better adapt and utilize the tool."

"The technical support from Apache is not good; support needs to be improved. I would rate them from one to ten as not good."

More Apache Flink cons

"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."

"I think Redpanda needs to increase the connector options."

"Redpanda needs more visibility and primarily greater access to documentation."

"One area for improvement is providing more examples."

"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."

"Redpanda can be improved in several ways, and the more I experiment with the product, the more limitations I find."

"In Redpanda, the areas that have room for improvement are in the clustering part."

"For me, I was trying to get a lot of data, but I would only get one day's worth of data, even though I asked how I could increase the retention size."

More Redpanda cons

Pricing and Cost Advice

"It's an open-source solution."

"The solution is open-source, which is free."

"Apache Flink is open source so we pay no licensing for the use of the software."

"It's an open source."

"This is an open-source platform that can be used free of charge."

"It's free. Everybody can use it, only support is paid."
