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.

Centralized visibility has streamlined daily monitoring and troubleshooting of message flows
The best features of Kpow for Apache Kafka are real-time monitoring and powerful troubleshooting capabilities. I especially appreciate how easy it is to inspect topics, browse messages, monitor consumer groups, and track consumer lag from a single dashboard. The search and message inspection features make it much faster to debug production issues without relying heavily on command-line tools. Kpow for Apache Kafka has had a positive impact on our organization. It has reduced the time required to monitor Kafka clusters and troubleshoot issues, allowing the team to identify and resolve problems much faster. Having a centralized dashboard with clear visibility into topics, consumer groups, and message flow has improved our operational efficiency and reduced our reliance on command-line tools. Overall, it has helped streamline our Kafka management and made it easier for both developers and operations teams to collaborate when investigating issues.

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."
"Among all of this, if I would talk about streaming, Apache Flink wins hands down, but there are other products like Apache Pulsar which I have no idea."
"This is truly a real-time solution."
"Apache Flink allows you to reduce latency and process data in real-time, making it ideal for such scenarios."
"Apache Flink provides faster and low-cost investment for me; I find it to have low hardware requirements, and it's faster with low code, meaning it's easy to understand for moving the streaming data."
"Allows us to process batch data, stream to real-time and build pipelines."
"Apache Flink offers a range of powerful configurations and experiences for development teams. Its strength lies in its development experience and capabilities."
"The top feature of Apache Flink is its low latency for fast, real-time data. Another great feature is the real-time indicators and alerts which make a big difference when it comes to data processing and analysis."
"Kpow for Apache Kafka makes development faster because integration with Kafka can be quite complex and requires significant research and development effort, however, with Kpow for Apache Kafka, you can use a simple integration process to handle all of these aspects."
"Overall, Kpow for Apache Kafka has scaled well with our environment and has remained responsive and reliable as our workload increased."
"Using Kafka instead of something such as IBM MQ is much cheaper, offering scalability and processing messages in parallel, which Kafka helps manage quite a lot, though you can have issues with duplicate processing."
"Kpow for Apache Kafka has positively impacted my organization and has been very beneficial."
"The best feature of Kpow for Apache Kafka is that it can actually scale up."
 

Cons

"There are more libraries that are missing and also maybe more capabilities for machine learning."
"In terms of improvement, there should be better reporting. You can integrate with reporting solutions but Flink doesn't offer it themselves."
"Apache Flink's documentation should be available in more languages."
"There is a learning curve. It takes time to learn."
"In terms of stability with Flink, it is something that you have to deal with every time. Stability is the number one problem that we have seen with Flink, and it really depends on the kind of problem that you're trying to solve."
"The TimeWindow feature is a bit tricky. The timing of the content and the windowing is a bit changed in 1.11. They have introduced watermarks. A watermark is basically associating every data with a timestamp. The timestamp could be anything, and we can provide the timestamp. So, whenever I receive a tweet, I can actually assign a timestamp, like what time did I get that tweet. The watermark helps us to uniquely identify the data. Watermarks are tricky if you use multiple events in the pipeline. For example, you have three resources from different locations, and you want to combine all those inputs and also perform some kind of logic. When you have more than one input screen and you want to collect all the information together, you have to apply TimeWindow all. That means that all the events from the upstream or from the up sources should be in that TimeWindow, and they were coming back. Internally, it is a batch of events that may be getting collected every five minutes or whatever timing is given. Sometimes, the use case for TimeWindow is a bit tricky. It depends on the application as well as on how people have given this TimeWindow. This kind of documentation is not updated. Even the test case documentation is a bit wrong. It doesn't work. Flink has updated the version of Apache Flink, but they have not updated the testing documentation. Therefore, I have to manually understand it. We have also been exploring failure handling. I was looking into changelogs for which they have posted the future plans and what are they going to deliver. We have two concerns regarding this, which have been noted down. I hope in the future that they will provide this functionality. Integration of Apache Flink with other metric services or failure handling data tools needs some kind of update or its in-depth knowledge is required in the documentation. We have a use case where we want to actually analyze or get analytics about how much data we process and how many failures we have. For that, we need to use Tomcat, which is an analytics tool for implementing counters. We can manage reports in the analyzer. This kind of integration is pretty much straightforward. They say that people must be well familiar with all the things before using this type of integration. They have given this complete file, which you can update, but it took some time. There is a learning curve with it, which consumed a lot of time. It is evolving to a newer version, but the documentation is not demonstrating that update. The documentation is not well incorporated. Hopefully, these things will get resolved now that they are implementing it. Failure is another area where it is a bit rigid or not that flexible. We never use this for scaling because complexity is very high in case of a failure. Processing and providing the scaled data back to Apache Flink is a bit challenging. They have this concept of offsetting, which could be simplified."
"The technical support from Apache is not good; support needs to be improved. I would rate them from one to ten as not good."
"PyFlink is not as fully featured as Python itself, so there are some limitations to what you can do with it."
"I am saying that the cloud version is quite expensive, and there's room for improvement since I've set up a test cluster on my own AWS account, and within the first couple of days, it already accumulated a bill close to $200-$300 with no activity on the cluster."
"To improve Kpow for Apache Kafka, I believe that even though the UI is really user-friendly, it can be made more intuitive."
"Kpow for Apache Kafka can sometimes be overkill if my data set is small because I will end up paying for the cluster and retaining it and managing the clusters."
"However, the default resource allocation is very limited."
"Kpow for Apache Kafka is a strong product, but there are a few areas where it could be improved."
